That's why NUMBEROCK put it all into this song about triangles that is filled with real-world connections. Triangles are all around us, so it is easy to make this song especially relevant to the lives of students. Learn how to classify triangles by their sides (scalene, isosceles, & equilateral) and by the angles (acute, obtuse, & right) in this ridiculously catchy rock song. »»-------------¤-------------««»»-------------¤-------------«« LYRICS: Isosceles triangles have two equal sides like this mountain we’re about to climb; and since one angle’s over ninety degrees, an obtuse triangle is what we see. If you add up every angle, there are one hundred eighty degrees in a triangle. If the length is equal on every side, we say it’s equilateral, like this road sign; and since every angle’s less than 90 degrees, an acute triangle it will also be. If skateboard ramps are your scene, with three different sides they’re called scalene. That triangle would also be called right if a ninety degree angle is inside. There are two ways to classify triangles: by their sides and their angles, like sails out on the high seas can be right or isosceles. Or look at the foot of this goose; it’s scalene and obtuse. When you break pool balls with a cue, they’re equilateral and acute. This video addresses the following standards: 4.G (Draw and identify lines and angles, and classify shapes by properties of their lines and angles.) 5.G (Classify two-dimensional figures into categories based on their properties.)

▶ SUBSCRIBE HAPPY LEARNING! http://bit.ly/HappyLearningTV Educational Videos and songs for Kids. Today we’re going to learn about triangles. Triangles are polygons with three sides... See?.. One, two, three... But ... There are different kinds of triangles, and we classify them by the length of their sides. Using this classification, we get three types of triangles: isosceles, equilateral and scalene. In Equilateral triangles, all the sides are the same length... Can you see how it is formed? Good! So this triangle is equilateral because its three sides are exactly the same. In an isosceles triangle, two sides are the same length... and one is different.... See how it’s formed?.. Great, so - this is an isosceles triangle, with two equal sides and one different one. And finally, let’s look at a scalene triangle: all three sides are a different length. See?.. Easy eh?.. A scalene triangle is the one with three different length sides; none of its sides are equal. ▶SUBSCRIBE TO HAPPY LEARNING! http://bit.ly/HappyLearningTV "Educational Videos and songs for Kids" Maybe if they didn’t have such strange names, it’d be easier to remember them... So let’s look again, just so we don’t forget. All triangles have three sides, and depending on the length of their sides, they can be classified like this: an equilateral triangle... all three sides are equal in length; an isosceles triangle... two sides are the same length and one is different; and a scalene triangle... all three sides are different in length. Easy, right? So, goodbye for now, everyone, and don’t forget to subscribe to Happy Learning!

And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.

For a complete lesson on the isosceles triangle theorem, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn that an isosceles triangle is composed of a base, two congruent legs, two congruent base angles, and a vertex angle. Students also learn the isosceles triangle theorem, which states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent; and the converse of the isosceles triangle theorem, which states that if two angles of a triangle are congruent, then the sides opposite those angles are congruent. Students are then asked to solve problems related to these theorems using Algebra.

You'll also discover that you sometimes have something left over (called a "remainder") when you divide. In 3rd grade you learned what a fraction is. Now you'll start adding, subtracting, multiplying, and comparing them. You'll also see how they relate to decimals. On other fronts, you'll learn how to convert between different units (which is super important when comparing the size and speed of robot unicorns in different countries) and continue your journey thinking about various shapes in two dimensions. Some of the foundational concepts of geometry (like lines, rays and angles) also get introduced.

Join Our Geometry Teacher Community Today! http://geometrycoach.com/Geometry-Lesson-Plans/?pa=MOOMOOMATH http://www.moomoomath.com/Definition-of-Scalene-Triangle.html What is a scalene triangle? Transcript Scalene Triangles Welcome to MooMooMath. Today we are talking about Scalene Triangles. A scalene triangle is one in which all three angles are different. So let's look at two examples. I'm going to mark these triangles 3 inches, 4 inches, and 5 inches. All three sides are different lengths. This triangle over here is marked such that all three sides are the same. The mark on the side represents equal lengths. This is actually an equilateral triangle. Now let's look at a scalene triangle based on angles. You have a forty five degree angle, a forty five degree angle, and a ninety degree angle, and over here you have a 60 degree angle, a 30 degree angle, and a ninety degree angle. So based on angles which of these is a scalene angle? This one here (circles the triangle with 60, 30, 90 degree angles) because all three angles are different or all three sides are different. The other triangle these two angles are the same meaning these two legs are the same so this one is actually what they call an isosceles triangle. So let's look at the rules. The definition is all sides are different lengths and all angles are different measures. So our 3, 4, 5, is our example. Hope this video was helpful.

What is a right triangle
 
01:08
Learn the essential definitions of triangles. A triangle is a polygon with three sides. Triangles are classified on the basis of its angles or on the basis of its side lengths. The classification of triangles on the bases of its angles are: acute, right and obtuse triangles. The classification of triangles on the bases of its side lengths are: scalene, isosceles and equilateral triangles. An acute triangle is a triangle with the three angles less than 90 degrees. A right triangle is a triangle with one of the angles equal to 90 degrees while an obtuse triangle is a triangle with one of the angles greater than 90 degrees. A scalene triangle is a triangle in which none of the sides is equal to another side. An isosceles triangle is a triangle in which two of the sides are equal to each other while an equilateral triangle is a triangle in which all the three sides are equal to each other. A perpendicular bisector is a line which divides a segment into two equal parts. #geometry #triangles

Learn the essential definitions of triangles. A triangle is a polygon with three sides. Triangles are classified on the basis of its angles or on the basis of its side lengths. The classification of triangles on the bases of its angles are: acute, right and obtuse triangles. The classification of triangles on the bases of its side lengths are: scalene, isosceles and equilateral triangles. An acute triangle is a triangle with the three angles less than 90 degrees. A right triangle is a triangle with one of the angles equal to 90 degrees while an obtuse triangle is a triangle with one of the angles greater than 90 degrees. A scalene triangle is a triangle in which none of the sides is equal to another side. An isosceles triangle is a triangle in which two of the sides are equal to each other while an equilateral triangle is a triangle in which all the three sides are equal to each other. A perpendicular bisector is a line which divides a segment into two equal parts. #geometry #triangles

Learn how to find the missing side of a triangle. A triangle is a polygon with three sides. Triangles are classified on the basis of the angles or on the basis of the sides. The classification of a triangle on the basis of the sides are: scalene, isosceles, and equilateral triangles. A scalene triangle is a triangle with none of the sides equal. An isosceles triangle is a triangle with two of the sides equal while an equilateral triangle is a triangle with the three sides equal. When given expressions representing the sides of a triangle with the type of the triangle also given, we can use the properties of the various types of triangles to evaluate the given expressions and hence find the measure of the sides of the triangle. #geometry #triangles
