In this lesson, we will learn how to use proportions in order to identify similar polygons.

Q1:

π΄ π΅ πΆ π· βΌ π π π πΏ and the perimeter of π΄ π΅ πΆ π· = 1 7 7 c m . Calculate the scale factor of similarity of π π π πΏ to π΄ π΅ πΆ π· and the perimeter of π π π πΏ .

Q2:

Given that π΄ π΅ πΆ π· βΌ πΈ πΉ πΊ π» , determine the length of πΈ π» .

Q3:

Are the two polygons similar?
