Geometry Quiz on Right Triangles

What is the HyL Congruence Theorem?

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

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

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

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