Question

angle ABC is taken by a dilation with center P and scale factor 13 to angle ABC. The measure of angle ABC is 21 what is the measure of angle ABC?

Answer 1

Explanation

One of the properties preserved under a dilation from the pre-image to the image is that the angle measures remain the same. In other words, the pre-image and image are similar. When two figures are similar, their corresponding angles are equal.

Thus, if the measure of angle ABC is 21, the measure of angle A'B'C' is also 21.

Answer

The measure of angle A'B'C' is 21.
