2. I can identify corresponding angles and corresponding sides in triangles and prove that triangles are congruent based on CPCTC.

3. Figures with the same shape and size You can determine whether two figures are congruent by comparing their corresponding sides and angles

4. congruent corresponding parts- their matching sides and angles. When you name congruent polygons, you must list corresponding vertices in the same order

5. Triangles with the same shape and size You can determine whether two triangles are congruent by comparing their corresponding sides and angles. CPCTC Corresponding Parts of Congruent Triangles are Congruent

6. If two angles of one triangle are congruent to two angles of another triangle, then the third angles are congruent.
