Question

Point O is the center of regular pentagon ABCDE. Find the image of the given point for the given rotation.r (144°,0) (A)The image of A is

Answer 1

The given point is the center, denoted as 0. This point is invariant under any rotation, this means that it remain in the same position. Then, the image after a 144 rotation is

Then, the answer after the 144 rotation is:

where letter A goes to D, B goes to E and so on.

Thats because each interior angle measure 72 degrees as shown:
