Answer:
210 degrees
Explanation:
In symmetrical rotation i.e for the polygon to appear to be in the same place
The angle of rotation = 360/number of sides of the polygon
Number of sides=12
Therefore, Angle of rotation = 360/12=30 degrees
For AB to map onto FG, the polygon will have been rotated symmetrically seven times.
Therefore, the angle of rotation such that AB maps onto FG
= 30 x 7
= 210 degrees.
