If a 12-sided regular polygon rotates about its center, at which angle of rotation will the image of the polygon coincide with the prelmage?
O A 750
B. 45
oc 360
D. 30
At the center of the polygon are twelve 30° angles - 360° / 12.If the polygon is rotated 30° the image (transformation) shall coincide with the preimage (the figure before transformation).
