TRIANGLE CONGRUENCE POSTULATES

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a postulate that states if two angles and a non-included side of one triangle are congruent to two angles and a non-included side of another triangle, then the triangles are congruent.

What is the included side in a triangle?

Back

The included side is the side that lies between two angles in a triangle.

What is the HL postulate in triangle congruence?

Back

The HL (Hypotenuse-Leg) postulate states that if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.

What is the difference between included angle and included side?

Back

The included angle is the angle formed by two sides of a triangle, while the included side is the side that lies between two angles.

Front

If two triangles have two pairs of congruent angles, what can be concluded about the triangles?

Back

If two triangles have two pairs of congruent angles, the triangles are congruent by the AAS postulate.
