Right Triangles Right Triangles

The theorems mentioned in this unit, were for ALL triangles.So, it should make perfect sense that they would apply to right trianglesas well.

Theorem

8-2

HL Postulate

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