**Corresponding Parts of Triangles**

If two triangles are similar, then the ratio of corresponding sides is equal to the ratio of the angle bisectors, altitudes, and medians of the two triangles. To find a missing angle bisector, altitude, or median, use the ratio of corresponding sides and the Triangle Bisector Theorem.

**Similar Triangles**

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.
