10/29/2020 Unit Activity: Perimeter and Area of Similar Quadrilaterals Task 2 Perimeter and Area of Similar Quadrilaterals In this unit, you recognized how the perimeter and the area of similar triangles compare with one another. Let’s consider whether these ideas apply to quadrilaterals—shapes that have four sides. Question 1 First you’ll study the perimeters of similar quadrilaterals. Open perimeter of similar quadrilaterals , and complete each step below. Part A Dilate quadrilateral ABCD with the origin as the center of dilation and a scale factor of 2.5. Record the side lengths of the corresponding sides in each quadrilateral. Round your answers to the hundredths place. Verify that the ratio of each side length of A′B′C′D′ to the corresponding side length of ABCD is equal to the dilation factor.
