For a complete lesson on similar triangles, go to http://www.MathHelp.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn that similar polygons have the same shape, and if two polygons are similar, then the corresponding angles are congruent, and the corresponding sides are in proportion. Students also learn that the scale factor is ratio of the lengths of two corresponding sides. Students are then asked to use these concepts to find missing angle measures and missing side lengths in similar figures.
