Give the angle of rotation of the following figures:-

Dear Brother

Square = 90?
Rectangle=180?
Equilateral triangle = 120?
Regular Hexagon = 60?
Circle = any angle... answer will be same
Semi circle = 180?



Explaination...
Sq. Has 4 sides so 4

Rect. Since has 4 sides but to get it again we have to rotate it half...as it only has 2 side equal

Eq.. triangle it has 3 side so 3

Hexagon since it 6 sides so 60
