Question

The pink trapezoid has been dilated to the blue trapezoid. What was the center of the dilation?

Answer 1

find two corresponding points between the blue and pink trapezoids. for example, I will pick the upper right corners on both shapes

Answer 2

then draw a straight line through the two points, and extend forever in both directions

Answer 3

keep going with all the points on the two shapes. all the lines you draw should intersect at one point. that one point is your center of dilation.

Answer 4

you are smart
