What are the criteria for triangle congruence?

Back

The criteria for triangle congruence are: 1) Side-Side-Side (SSS), 2) Side-Angle-Side (SAS), 3) Angle-Side-Angle (ASA), 4) Angle-Angle-Side (AAS), and 5) Hypotenuse-Leg (HL) for right triangles.

Define Side-Side-Side (SSS) Congruence.

Back

SSS Congruence states that if three sides of one triangle are equal to three sides of another triangle, then the two triangles are congruent.

Define Side-Angle-Side (SAS) Congruence.

Back

SAS Congruence 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.

Define Angle-Side-Angle (ASA) Congruence.

Back

ASA Congruence 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.

Define Angle-Angle-Side (AAS) Congruence.

Back

AAS Congruence states that if two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, then the triangles are congruent.

What is Hypotenuse-Leg (HL) Congruence?

Back

HL Congruence applies to right triangles and states that if the hypotenuse and one leg of one right triangle are equal to the hypotenuse and one leg of another right triangle, then the triangles are congruent.

How can you determine if two triangles are congruent using SSS?

Back

To determine if two triangles are congruent using SSS, measure the lengths of all three sides of both triangles. If all three pairs of corresponding sides are equal, the triangles are congruent.

How can you determine if two triangles are congruent using SAS?

Back

To determine if two triangles are congruent using SAS, measure two sides and the included angle of both triangles. If the two sides and the included angle are equal, the triangles are congruent.

What is the importance of corresponding angles in triangle congruence?

Back

Corresponding angles are important in triangle congruence because they must be equal for the triangles to be congruent, ensuring that the triangles maintain the same shape.
