  1. Congruence in Right Triangles Lesson 4-6

  2. hypotenuse legs Right Triangles • Parts of a Right Triangle: • Legs: the two sides adjacent to the right angle • Hypotenuse: the longest side and the side opposite the right angle

  3. What is the Hypotenuse-Leg (HL) Thm? • If the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent. Congruent triangles by HL Thm

  4. In order to use HL Theorem… • Before your congruence statement, you need to state: • …. Are right angles | defn of perpendicular • …. Are right triangles | defn of right triangles • . • . • . … | HL Thm
