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 of one triangle are equal to two sides and the included angle of another triangle.

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 of one triangle are equal to two angles and the corresponding non-included side of another triangle.

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a criterion for triangle congruence applicable to right triangles where the hypotenuse and one leg of one triangle are equal to the hypotenuse and one leg of another triangle.

What is the SSA condition in triangle congruence?

Back

SSA stands for Side-Side-Angle, which is not a valid criterion for triangle congruence as it can lead to ambiguous cases.

If two triangles have two sides equal and the included angle is not known, can we determine congruence?

Back

No, we cannot determine congruence with just two sides and a non-included angle (SSA condition) as it may lead to different triangle configurations.

How can you prove two triangles are congruent using SAS?

Back

To prove two triangles are congruent using SAS, show that two sides of one triangle are equal to two sides of another triangle and that the angle between those sides is also equal.
