  2. 5.4 Hypotenuse-Leg (HL) Congruence Theorem Objective: To use the HL Congruence Theorem and summarize congruence postulates and theorems.

  3. Side Names of Triangles • Right Triangles: side across from right angle is the hypotenuse, the remaining two are legs. leg hypotenuse leg

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

  5. 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. A X B C Y Z

  6. Examples: Determine if the triangles are congruent. State the postulate or theorem.
