Triangle Congruence

Front

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a theorem used to prove the congruence of right triangles.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a theorem stating that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a theorem stating that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a theorem stating 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, the triangles are congruent.

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a theorem stating that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

What is the Hypotenuse-Leg (HL) theorem used for?

Back

The HL theorem is used to prove the congruence of right triangles when the hypotenuse and one leg are known to be equal.

When can you use the SSS theorem?

Back

You can use the SSS theorem when you know all three sides of two triangles are equal.

Front

When can you use the SAS theorem?

Back

You can use the SAS theorem when you know two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.
