5. Similar figures have the same shape but not necessarily the same size. If two figures are similar, then the measures of the corresponding angles are equal and the ratios of the lengths of the corresponding sides are proportional.

6. Matching sides of two or more polygons are called corresponding sides, and matching angles are called corresponding angles.

7. Determining whether two triangles are similar
