# Unit 4 Congruent Triangles Quiz 4 1 Answer Key

## Introduction

Geometry is one of the most challenging subjects for most high school students. It is a branch of mathematics that deals with the study of shapes, sizes, positions, and dimensions of objects. One of the most crucial topics in geometry is congruent triangles. The concept of congruence in triangles is the foundation of many geometry problems. In this article, we will discuss the Unit 4 Congruent Triangles Quiz 4 1 Answer Key in a relaxed English language.

## What are Congruent Triangles?

Congruent triangles are two triangles that have the same size and shape. The sides and angles of congruent triangles are equal. When two triangles are congruent, it means that they can be superimposed on each other, and they will match exactly. Congruent triangles are a fundamental concept in geometry, and they are essential in many geometric proofs.

### Properties of Congruent Triangles

There are several properties of congruent triangles that are essential to geometry. The first property is the side-side-side (SSS) congruence postulate. This postulate states that if three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent. The second property is the side-angle-side (SAS) postulate. This postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent. The third property is the angle-side-angle (ASA) postulate. This postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
