1-1b Slide 1 of 2 (over Lesson 6-4) http://yourcharlotteschools.net/Schools/PCHS/Pellegrino_site/Chapter6Section5.ppt#262,8

You will learn to use tests for _________ of ____ triangles. 1) _________ 2) ____ congruenceright hypotenuse legs http://yourcharlotteschools.net/Schools/PCHS/Pellegrino_site/Chapter6Section5.ppt#262,8

In a right triangle, the side opposite the right angle is called the _________. hypotenuse The two sides that form the right angle are called the ____. legs leg http://yourcharlotteschools.net/Schools/PCHS/Pellegrino_site/Chapter6Section5.ppt#262,8

Recall from earlier this unit, we studied various ways to prove triangles to be congruent: In 8-1, we studied two theorems and A B C R S T A B C R S T http://yourcharlotteschools.net/Schools/PCHS/Pellegrino_site/Chapter6Section5.ppt#262,8

Recall from earlier this unit, we studied various ways to prove triangles to be congruent: In 8-2, we studied two theorems and R S T A B C R S T A B C http://yourcharlotteschools.net/Schools/PCHS/Pellegrino_site/Chapter6Section5.ppt#262,8

The theorems mentioned in this unit, were for ALL triangles. So, it should make perfect sense that they would apply to right triangles as well. Theorem 8-2 HL Postulate If the hypotenuse and a leg on one right triangle are congruent to the hypotenuse and corresponding leg of another right triangle, then the triangles are congruent.
