Unit 4 Overview
G.GSR.5: Describe dilations in terms of center and scale factor and use these terms to describe
properties of dilations; use the precise definition of a dilation to describe similarity and establish the
criterion for triangles to be similar; use these terms, definitions, and criterion to prove similarity, model,
and explain real-life phenomena.

Unit 4 Learning Expectation:
G.GSR.5.1 - Verify experimentally the properties of dilations.
G.GSR.5.2 - Given two figures, use and apply the definition of similarity in terms
of similarity transformations.
G.GSR.5.3 - Use the properties of similarity transformations to establish criterion
for two triangles to be similar. Use similarity criteria for triangles to solve
problems and to prove relationships in geometric figures.
G.GSR.5.4 - Construct formal proofs to justify and apply theorems about triangles.
