Learning Targets and Learning Criteria 
• use dilations to prove similar figures. • define similarity as a composition of rigid motions followed by dilations in which angle measure is preserved and side length is proportional. • show and explain that when two angle measures are known (AA), the third angle measure is also known (Third Angle Theorem). • apply theorems, postulates, or definitions to prove theorems about triangles and proportional parts of parallel lines, including: • use triangle similarity to solve problems
