The angle of rotation at which point a′ coincides with point d is_
°.

The angle of rotation at which point A′ coincides with point D is 144° counterclockwise or 216° clockwise.

Step-by-step explanation:

The given figure represents a regular pentagon. It means the central angle between two consecutive vertices is

The vertex D is 2nd vertex from counterclockwise. So, the counterclockwise angle between A and D is

The angle of rotation at which point A′ coincides with point D is 144° counterclockwise.

The angle of rotation at which point A′ coincides with point D is 216° clockwise.
