By what minimum angle does a regular hexagon rotate so as to coincide with its original position for the first time?
उत्तर
A regular hexagon must be rotated through a minimum angle of 60°. So, that it can coincide with its original position for the first time. Because the angle of rotation of hexagon
= `360^circ/"Number of sides"`
= `360^circ/6`
= 60°
