TODAY: We continue with our lesson on 8-1. We have a right triangle and an altitude in it that stems from its right angle's vertex. Yesterday we discovered the 3 resulting right triangles are SIMILAR. Therefore, when we write the proportions, theorems 8-2 and 8-3 result.
GET THE NEW HANDOUT!
TOMORROW: another handout and practice on theorems 8-2 and 8-3!
