After rotating by 60° about a centre, a figure looks exactly the same as its original position. At what other angles will this happen for the figure?

Text Solution

Verified by Experts

An object when rotated in a particular direction, around a point, it is known as rotational symmetry,
Similarly , rotational symmetry exists when the turned shape is identical to the origin.
Thus, if the figure looks the same as its original position by rotating at an angle of `60°, `
it will also look the same by rotating at an angle of `120°, 180°, 240°, 300°, 360° `as these are its multiples.
