Front

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a criterion for the congruence of right triangles.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion for triangle congruence where two angles and the included side are known.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence where two sides and the included angle are known.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a criterion for triangle congruence where two angles and a non-included side are known.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a criterion for triangle congruence where all three sides of one triangle are equal to the corresponding sides of another triangle.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

Front

When can we say two triangles are congruent using the SSS criterion?

Back

Two triangles are congruent using the SSS criterion if all three sides of one triangle are equal to the three sides of another triangle.

Front

When can we say two triangles are congruent using the SAS criterion?

Back

Two triangles are congruent using the SAS criterion if two sides and the included angle of one triangle are equal to the corresponding parts of another triangle.

Front

When can we say two triangles are congruent using the ASA criterion?

Back

Two triangles are congruent using the ASA criterion if two angles and the included side of one triangle are equal to the corresponding parts of another triangle.

Front

When can we say two triangles are congruent using the AAS criterion?

Back

Two triangles are congruent using the AAS criterion if two angles and a non-included side of one triangle are equal to the corresponding parts of another triangle.
