Question

In the figure polygon ABCD is transformed to create polygon A’B’C’D’. This transformation is a ____ by a factor of ____.

Answer 1

In the figure polygon ABCD is transformed to create polygon A’B’C’D’. This transformation is a horizontal stretch by a factor of 2.

Explanation:

Dilation is a combination of vertical and horizontal stretch. In this case, the stretch os only horizontally applied.

We can see in the picture that the measure of figure ABCD in the x-axis is 2 units long and of Figure A'B'C'D' is 4 units long (double than ABCD). Then the stretch factor is 2.
