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 HL stand for in triangle congruence?

Back

HL stands for 'Hypotenuse-Leg', a theorem applicable to 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.
