This geometry video tutorial provides a basic introduction on similar triangles and similar figures. It explains how to find the missing side using the proportions of similar triangles and even similar trapezoids. It explains how to solve for x as it relates to missing sides and missing angles. It discusses how to calculate the enlargement ratio and how to use it to determine the perimeter area of another triangle. This tutorial contains plenty of examples and practice problems.
