a shape with rotational symmetry can be rotated around a point so that all of its characteristics are maintained
kirza4 [7]

The correct answer to this is “True”.

Symmetry signifies balance and form. An object with rotational symmetry will still look the same after a rotation. Since it maintains its shape and figure after being rotated, therefore its characteristics such as length of the diagonals, the angles of each corner, or parallelism of opposite sides will remain the same.
