Section 4.3 – Analyzing Triangle Congruence

Angle-Angle-Side (AAS) Congruence Theorem

If 2 angles and the non-included side of one triangle are congruent to the corresponding 2 angles and non-included side of another triangle, then the 2 triangles are congruent.

Right Triangle Congruence

Hypotenuse-Leg (HL) Theorem

If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and corresponding leg of another right triangle, then the 2 right triangles are congruent.
