## 4.6:Congruence in Right Triangles

Objective: To prove triangles congruent by the HL Theorem

### Right Triangles

Legs

Special Case where there is an ‘SSA’ congruence rule

Has to be a right triangle!!

Hypotenuse

### Hypotenuse-Leg (HL) Theorem

If the hypotenuse and a leg of one right triangle are to a hypotenuse and a leg of another right triangle, then the 2 triangles are .

### To use the HL theorem, you must show the following 3 conditions are met:

• You have 2 right triangles

• The triangles have hypotenuses

• The triangles have one pair of legs
