Right triangle congruence theorems; Module 5.4

Theorems 4.6 Leg-Leg Congruence LL

If the legs of one right triangle are congruent to the corresponding legs of another right triangle, then the triangle are congruent.

Theorem 4.7 Hypotenuse-Acute Congruence HA

If the hypotenuse and acute angle of one right triangle are congruent to the hypotenuse and corresponding acute angle of another right triangle, then the two triangles are congruent

Theorem 4.8: Leg-Angle Congruence LA

If one leg and an acute angle of one right triangle are congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent

Theorem 4.9 Hypotenuse-Leg Congruence HL

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