HL = Hypotenuse & Leg of a right triangle are congruent to another right triangle.
Step-by-step explanation:
To prove a triangle is congruent to another using HL, you must prove that the triangles have a corresponding 90 degree angles, corresponding congruent hypotenuse side lengths, and corresponding congruent hypotenuse legs.
The triangles here both have 90 degree angles a marked on the figure.
Two ways to Prove:
Reflexive property for the hypotenuse. Properties of a rectangle to prove equal legs.
