Perform and describe translations, reflections, rotations, and dilations of figures on the coordinate plane.

Grade 6-8Intermediate55 min

About This Lesson

In this lesson you'll move, flip, turn, and resize shapes on a coordinate plane! Transformations are the foundation of animation, video games, architecture, and graphic design.

Essential Question

Look at these two triangles on the grid. Are they the same shape and size? How did one become the other?
