45 Degrees is the smallest angle of rotational symmetry that maps a regular octagon onto itself

Solution-

A regular octagon has 8 equal angles and 8 equal sides.  

When rotating an octagon around its center, 1/8th of a full-circle rotation will cause adjacent sides to coincide on each other.

A circle has 360° and (1/8)th of 360° = 45°.  

Hence, a minimum of 45° rotation counterclockwise or clockwise(as it is symmetric so the order doesn't matter) puts each of the edges over the position where an adjacent edge was located before.

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !
