7 C) 35 8 D) No solution. #15) If triangle ABC is similar to triangle EFG, find x. 6 1 A) 1 3 B) 3 C) 9 2 D) 2 9 Short answer. Use complete sentences. A definition covers all situations. An example is a specific situation. #16) Define similar polygons. Also, give an example of similar polygons. Definition Example: #17) Define congruent polygons. Properties of Similar Polygons Two polygons are similar if 1. they have the same number of sides. 2. their corresponding angles are congruent. 3. their corresponding sides have a constant ratio (in other words, if they are proportional). Typically, problems with similar polygons ask for missing sides. The ratios are the same, so the shapes are similar.

Jan 21, 2015 · 7-3 similar polygons 1. 7-3 Similar Polygons (7-2 in the Pearson Textbook) Chapter 7 Ratio, Proportion and Similarity Objective: I can state and apply the properties similar polygons. 2. Two polygons are similar (~) if their vertices can be paired so that: 1. corresponding angles are congruent. 2. Corresponding sides are in proportion.

11 ― 4 = 7 In a similar manner, we can calculate the length of the other missing side using 14−8=6. This gives us the lengths of all the sides as shown in the figure below. 8 11 14 4 7 6 Now that we have all the lengths of the sides, we can simply calculate the perimeter by adding the lengths together to get 4+14+11+8+7+6=50.

Top Answer. Wiki User Answered . 2010-02-27 15:51:44. ... The perimeters of two similar polygons have the same ratio as the measure of any pair of corresponding sides. So the ratio of the measure ...

similarity ratio is the ratio of two corresponding linear measurements in a pair of similar figures. The following similarity ratios can be written for ∆ and ∆ . =6 3 =2 =10 5 =2 =4 2 =2 Like congruence, similarity is a transitive relation. The Transitive Property of Similarity states that if a ∼ b, and b ∼ c, then a ∼ c.
