Back to Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, and dilations — Problem 2 · Task Set 24
Exercises: Understand Similarity Through Sequences of Transformations
Work through each section in order. A dilation centered at the origin with scale factor $k$ maps $(x, y)$ to $(kx, ky)$. The scale factor is the ratio of corresponding side lengths. Show your work where indicated.

Recall / Warm-Up
These problems review skills you already know: corresponding sides, dilation rules, and the three rigid motions.
1.
A sequence of transformations uses only translations, reflections, and rotations (no dilation). Two figures connected by such a sequence are always which of the following?
