Lessons 50 & 55: Geometric mean Midsegments & Related Theorems

2. Geometric Mean
Goals: To define the relationship between a midsegment of a triangle and the side parallel. To use similarity relationships within right triangles.
Essential Understandings: The geometric mean between two numbers is the square root of their products. The altitude of a right triangle divides the triangle into three similar triangles. The midsegment of a triangle is parallel to and half the size of side it does not intersect.
