Answer 1

Answer:

Step-by-step explanation:

The centre of rotation of a square is the point of intersection of its diagonals and the angle of rotation is 90°. So, the order of rotational symmetry of a square is 4. The centre of rotation of a circle is the centre of the circle and it has rotational symmetry around the centre for every angle.

Rectangle: Intersection point of diagonals

Equilateral triangle: Intersection point of medians

Regular hexagon: Intersection point of diagonals

Regular pentagon: 72° shall be the angle of rotation for the Pentagon. So when you draw a line from each corner at 72(degree) the point where all the lines meet is it's centre of rotation
