Side Names of Triangles• Right Triangles: side across from right angle is

the hypotenuse, the remaining two are legs.

Examples: Tell whether the segment is a leg or a hypotenuse.

Hypotenuse- Leg (HL) Congruence Theorem:

• If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and leg of a second right triangle, then the two triangles are congruent.

• Example: because of HL.
