Today we talked about how similar right triangles are formed when an altitude is drawn from the right angle of a right triangle. The Geometric Mean (Altitude) and The Geometric Mean (Leg) Theorems are good shortcuts to remember when solving for missing sides of these right triangles.
Tonight's homework is P. 453-454 #5,9,15,19,20,21
Check out this animation to help you understand how geometric means are used in right triangles: http://www.classzone.com/cz/books/geometry_2007_na/resources/applications/animations/9_1.html
