What does SSS stand for in triangle congruence?

Back

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

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, which states 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.

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, which states 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 does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, which 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, the triangles are congruent.

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, which is a specific case for right triangles stating that if the hypotenuse and one leg of one right triangle are equal to the hypotenuse and one leg of another right triangle, the triangles are congruent.

What is the first statement in the reason column of a proof?

Back

The first statement in the reason column of a proof is 'Given', which refers to the information provided in the problem.

Front

Are triangles with two sides equal and a non-included angle equal congruent?

Back

No, triangles with two sides equal and a non-included angle (SSA) are not necessarily congruent.

Front

If two triangles have equal corresponding angles, what can be concluded?

Back

If two triangles have equal corresponding angles, they are similar, but not necessarily congruent unless their corresponding sides are also equal.
