# Understanding Triangle Congruence Theorems and Their Common Core Geometry Homework Answer Keys

Triangle congruence theorems are a critical aspect of geometry. They are so important because they provide a way to determine if two triangles are equal—or congruent—to one another. A triangle congruence theorem is an equation, or set of equations, that defines the relationship between the sides and angles of two triangles. The most common triangle congruence theorem is the SAS (side-angle-side) theorem.

The SAS theorem states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent. This theorem can be used to solve a variety of geometry problems and is the basis for most other triangle congruence theorems. It is also commonly used in Common Core Geometry homework, with answer keys available to help students understand the concepts.

## The SSS and ASA Theorems The SSS (side-side-side) theorem states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent. This can be used to solve problems that deal with the relationship between the sides of two triangles. The ASA (angle-side-angle) theorem states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent. This can be used to solve problems that deal with the relationship between the angles and sides of two triangles.

## The AAS and HL Theorems The AAS (angle-angle-side) theorem states that if two angles and the non-included side of one triangle are equal to two angles and the non-included side of another triangle, then the triangles are congruent. This can be used to solve problems that deal with the relationship between the angles and non-included sides of two triangles. The HL (hypotenuse-leg) theorem states that if the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, then the triangles are congruent. This can be used to solve problems that deal with the relationship between the hypotenuse and legs of two right triangles.

## Common Core Geometry Homework Answer Keys Common Core Geometry homework often requires students to use triangle congruence theorems to solve problems.
