Introduction to similar triangles Watch the next lesson: https://www.khanacademy.org/math/geometry/similarity/old_school_similarity/v/similar-triangles-part-2?utm_source=YT&utm_medium=Desc&utm_campaign=Geometry Missed the previous lesson? https://www.khanacademy.org/math/geometry/similarity/cc-solving-prob-similar-tri/v/challenging-similarity-problem?utm_source=YT&utm_medium=Desc&utm_campaign=Geometry Geometry on Khan Academy: We are surrounded by space. 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. About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content. For free. For everyone.

This geometry video tutorial provides a basic introduction on similar triangles and similar figures. It explains how to find the missing side using the proportions of similar triangles and even similar trapezoids. It explains how to solve for x as it relates to missing sides and missing angles. It discusses how to calculate the enlargement ratio and how to use it to determine the perimeter area of another triangle. This tutorial contains plenty of examples and practice problems.

Learn about dilations. A dilation is the transformation of a shape by a scale factor to produce an image that is similar to the original shape, but is different in size to the original shape. A dilation that creates a larger image is called an enlargement or a stretch while a dilation that creates a smaller image is called a reduction or a shrink. The measures of the sides of the original shape and the corresponding sides of the image are proportional. And the distance of the parts of the original shape from the origin are proportional to the distance of the corresponding parts of the image.

Learn how to solve for the unknown in a triangle divided internally such that the division is parallel to one of the sides of the triangle. The triangle proportionality theorem states that if a line is parallel to one side of a triangle and it intersects the other two sides, then it divides those sides proportionally. Thus, with the aid of the triangle propotionality theorem, we can solve for the unknown in a triangle divided proportionally. #geometry #similartriangles

How to construct a dilation
Views: 32418 LongoWTHS

02:02
If two triangles are mathematically similar, then all of the sides have been enlarged by the same scale factor. First you will have to calculate the scale factor of the enlargement by dividing two matching sides. Once you have calculated this scale factor, you can then multiply and divide by it to work out the other side lengths that are missing in the two triangles.

How similarity ratios are scale factors, drawing and describing dilations, how the pre-image and image of dilations are similar, similarity transformations, and finally determining whether polygons are similar.

For a complete lesson on similar triangle proofs, go to http://www.MathHelp.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar (Angle-Angle Similarity Postulate, or AA Similarity Postulate). Students also learn that the scale factor is ratio of the lengths of two corresponding sides. Students are then asked to use these concepts to determine whether given triangles are similar, and to find the missing side lengths in similar triangles.

This video focuses on how to find the area of similar triangles. In this video, we are given the length of one pair of corresponding sides in two similar triangles. Also, we know the area of one triangle. With this information, we need to find the area of the other triangle. To solve this problem, we use the theorem that states that if two triangles are similar, then the ratio of their areas is the square of the ratio of their sides.
