Answer: 60°, 72°, 90°, 120° and 180°
Step-by-step explanation:
To calculate the angle of rotational symmetry of a shape or polygon, you make use of this formula
[tex]\frac{360}{n} where n is the number of sides of the shape[/tex]
example for a Square with 4 sides. the angle of rotational symmetry is 360/4 =90°.
