Description: Identifying all the properties of shapes that are preserved under some rigid transformations, and all the properties that aren't preserved. What we're going to do in this video is think about what properties of a shape are preserved or not preserved, as they undergo a transformation. In particular, we're gonna think about rotations and reflections in this video. And both of those are rigid transformations which means that the length between corresponding points do not change.*Teacher Advisor is 100% free.
