Question

All circles are similar figures. A Single transformation is applied to the circle with center M to create another circle with center N. Which statement about the transformation is true?

Answer 1

I believe it is A

Answer 2

A dilation was applied because the diameter of the circle decreased.

Explanation:

Dilation is a process of either increasing or decreasing the size of a given figure without changing its shape. The resizing process make use of a scale factor to produce a dilated image of the given figure.

In the given question, it can be observed that the circle with center M has a diameter of 6 units, while that with center N has a diameter of 3 units. Thus circle M has been dilated with a scale factor of
`(1)/(2)` to produce circle N.

Therefore, a dilation was applied because the diameter of the circle decreased.
