1. Han's teacher asked him to draw a polygon similar to polygon A. Here is his work.
Which explanation shows that polygons A and C are similar to each other?


A. Use a protractor to measure all four angles in polygon A and all four angles in
polygon C. Since each angle in polygon A has a matching angle measure in
polygon C, the polygons are similar.
Since each side in polygon C is three times as long as the corresponding side in
polygon A, the figures are similar.
C. Dilate polygon C with center at the upper-left vertex and a scale factor of
Then, translate 7 units to the left. Since polygon C can be taken to polygon A
with a dilation followed by a translation, the figures are similar.
D. Dilate polygon C with center at the upper-right corner and a scale factor of 3.
Since polygon C can be taken to polygon A with a dilation, the polygons are
similar.
