This quiz and corresponding worksheet assess your understanding of CPCTC, or corresponding parts of congruent triangles are congruent. Practice problems assess your knowledge of this geometric theorem as well as the application of given information to determine that triangles are congruent.

In this assessment you will be tested on your ability to explain how triangles are congruent by using:

- CPCTC
- Theorem expressions
- Various angles

**Making connections**- use understanding of the concept CPCTC, or corresponding parts of congruent triangles are congruent**Problem solving**- use acquired knowledge to determine triangle congruency and solve practice problems**Knowledge application**- use your knowledge to answer questions about congruent triangles

To learn more about congruency in triangles, review the accompanying lesson on Congruence Proofs: Corresponding Parts of Congruent Triangles. This lesson covers the following objectives:

- Understand how triangles are congruent
- Use given information about triangles to determine their congruency
- Use CPCTC to explain matching triangle angles and sides
- Apply CPCTC to mathematical proofs
