How to prove congruent right triangles using the hypotenuse leg theorem. In words, if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of a second right triangle, then the triangles are congruent. Congruent triangles - Hypotenuse and leg of a right triangle. HL.

Feb 5, In this lesson, we'll learn about the hypotenuse leg theorem. This theorem enables us to prove two right triangles are congruent based on just. HL is an important theorem which is utilized in order to prove two right-angled triangles congruent to each other. It is also known as Hypotenuse leg theorem or . There are five ways to find if two triangles are congruent: SSS, SAS, ASA, AAS HL stands for "Hypotenuse, Leg" (the longest side of a right-angled triangle is.

This packet should help a learner seeking to understand how to use the triangle congruence theorem (Hypotenuse-Leg) to prove triangles congruent. The HLR (Hypotenuse-Leg-Right angle) theorem — often called the HL theorem — states that if the hypotenuse and a leg of one right triangle are congruent to. Learn the Hypotenuse Leg (HL) Theorem, use the HL Theorem to prove congruence in right triangles, and learn that corresponding parts of congruent triangles.
