Classify each statement as true or false. 1. Every polygon is similar to itself. 2. All triangles are similar. 3. All rectangles are similar. 4. All squares are similar. S. If two polygons are each similar to a third polygon, then the two polygons are similar to each other. The perimeter of a square, with a side length of s, is 4s. 6. 7. The ratio of the measures of two corresponding angles of two similar polygons is 1:1. 8. If two quadrilaterals are similar, then the quadrilaterals must be rectangles. 9. If two polygons are similar, then they are congruent. 10. If two triangles have the same perimeter, then they are congruent. 11. If the ratio of the lengths of two corresponding sides of two similar triangles is 1:1, then the triangles are congruent. an exercises 12-17, state why the polygons are, or are not, similar. 12. 13. 14.
