In this lesson we are going to go over similar polygons. We know that polygons are shapes that have three or more sides. These sides have to be enclosed, and straight. Two polygons are similar if and only if their corresponding angles are congruent, and the measures of their corresponding sides are proportional. An important thing to remember is a scale factor, which is the ratio of the lengths of two corresponding sides of two similar polygons. You'll use this a lot when talking about similar polygons. Through the examples you'll learn how to determine if each pair of figures is similar, and how to find the unknown sides.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
