The HL Theorem - Lesson 3-8
Today, we learned a new theorem called HL (Hypotenuse, Leg):
After we stated this, I decided that we should prove it...so, here we go!
We then went over an example that used this "postulate." Make sure that when you use this as a reason in a proof, you correctly reference the numbers of the previous steps that allow you to use it (they should be in the order of right angles, hypotenuse, legs).
