Pod-cast:



Example problems:Find BE similar_triangle_2.gif
Use the rule related to parallel lines, cross multiply and solve.

36 = 8x
4.5 = x

Find (X)

For this problem you must use the full sides of triangles as a solution. The parallel rule does not work here. The problem asks you to find x. Here is the solution:
