Congruent triangles (conceptual identification)

What you'll learn

1. Define congruence for triangles as having all corresponding sides and angles equal
2. Identify corresponding parts of congruent triangles from diagrams with tick marks and arc marks
3. Write congruence statements with vertices in corresponding order
4. Use known congruence between triangles to find missing side lengths and angle measures

Prerequisites

• Triangle angle sum and exterior angle theorem
