Triangle Congrruency

1. Congruence & Transformation- translations, reflections, and rotations

2. Congruent Triangles- corresponding angles and corresponding sides are in the same position in polygons. Two polygons are congruent polygons.

3. Triangle Congruence- triangle rigidity gives a shortcut for proving two triangles congruent. SSS and SAS

4. Classifying Triangles- Acute, Equiangular, right, obtuse, Equalateral, isosceles, scalene

5. Angle Relationships in Triangles- interior and exterior angles
