Triangle Congruence: HL

Front

What are the five ways to prove triangles congruent?

Back

SSS, ASA, AAS, SAS, HL

Front

Which method is NOT a valid test for triangle congruence?

Back

SSA

Front

What does SSS stand for in triangle congruence?

Back

Side-Side-Side: 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

Side-Angle-Side: 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 ASA stand for in triangle congruence?

Back

Angle-Side-Angle: 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.

Front

What does AAS stand for in triangle congruence?

Back

Angle-Angle-Side: If two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, the triangles are congruent.

Front

What does HL stand for in triangle congruence?

Back

Hypotenuse-Leg: In right triangles, if the hypotenuse and one leg of one triangle are equal to the hypotenuse and one leg of another triangle, the triangles are congruent.

Front

Can SSA be used to prove triangle congruence?

Back

No, SSA does not guarantee triangle congruence.

Front

If two triangles have two sides of equal length and the angle between them is equal, what can be concluded?

Back

The triangles are congruent by the SAS postulate.

Front

If two triangles have two angles of equal measure and the side opposite one of the angles is equal, what can be concluded?

Back

The triangles are congruent by the AAS postulate.
