Similar Polygons-two polygons such that their corresponding angles are congruent and the lengths of corresponding sides are proportional. exmaple:
Scale Factor- the ratio of the length of two corresponding sides
Theorem 6.1 Perimeters of Similar Polygons-If two polygons are similar, then the ratio of their perimeters is equal to the ratios of their corresponding side lengths.
Problem 1: AC:AB is 3:7
Problem 2: The perimiter of figure one is 40. The ratio of figure one:two is 2:1
