Similar shapes & transformations (Full video)

Khan Academy

Supporting grades: 8

Description: Sal is given pairs of polygons, and then he determines whether they are similar by trying to map one onto the other using angle-preserving transformations. Created by Sal Khan. If through some combination of translations, rotations, reflections, and dilations, I can make them sit on top of each other. And similarity allows us to use dilations, which essentially means scale up one of the figures up or down. We would only be translating, rotating, and reflecting.
