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 
Classroom Activities 
Geometry Nation Study Guides will only be distributed to Periods 7 & 8 since they do not have Geometry Nation Workbook. Period 2 needs to bring Geometry Nation Workbook to every Geometry class. Monday (2nd Period) / Tuesday (7th & 8th Periods) Review the IXL assignments that are due:
