Theorem 4.6 Hypotenuse­Leg (HL) Theorem
If the hypotenuse and a leg one right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.
Key Concept: Conditions for HL Theorem
The use the HL Theorem, the triangles must meet three conditions.
*There are two right triangles.
*The triangles have congruent hypotenuses.
*There is one pair of congruent legs.
