You to whoever !
using the tool above (see pic), determine the center of rotation. select the correct center of rotation below.
answer choices:
-e
-d
-n
-o
-m
part two:
what is the angle of rotation in degrees? enter a numerical value only.

Step-by-step explanation:

The segment joining an original point with its rotated image forms a chord of the circle of rotation containing those two points. The center of the circle is the center of rotation.

This means you can find the center of rotation by considering the perpendicular bisectors of the segments joining points with their images. Here, the only proposed center that is anywhere near the perpendicular bisector of DE is point M.

Segment AD is perpendicular to corresponding segment FE, so the angle of rotation is 90°. (We don't know which way (CW or CCW) unless we make an assumption about which is the original figure.)

b) well because you get well
