Introduction to Congruent Triangles
Congruent triangles are triangles that have the same size and shape. This means that corresponding sides and angles of the triangles are equal. In this unit, we will explore different methods to prove that two triangles are congruent. Homework 5 is designed to test your understanding of these concepts and problem-solving skills.
Key Concepts Covered in Unit 4 Homework 5
- Triangle Congruence: Understanding when two triangles are congruent

Sample Problems for Unit 4 Congruent Triangles Homework 5
Let’s look at some sample problems you might encounter in Unit 4 Homework 5:
Problem 1:
Given: Triangle ABC ≅ Triangle DEF
Prove: Angle A ≅ Angle D
Solution:
Since Triangle ABC is congruent to Triangle DEF, we know that corresponding angles are congruent. Therefore, Angle A ≅ Angle D.
Problem 2:
Given: Triangle XYZ ≅ Triangle UVW
Prove: Side XY ≅ Side UW
Solution:
By the CPCTC theorem, if two triangles are congruent, then their corresponding sides are congruent. Thus, Side XY ≅ Side UW.
