Question 13: The order of rotational symmetry of a figure is 2. Find the angle of rotational symmetry of the figure.
A) 180°
B) 90°
C) 60°
D) 360°
Explanation: The angle of rotational symmetry = 360° ÷ Order of rotational symmetry. Therefore, the angle of rotational symmetry = 360°/2 = 180°
Question 14: The angle of rotational symmetry of a figure is 60°. Find the order of rotational symmetry of the figure.
A) 1
B) 2
C) 4
D) 6
Explanation: The order of rotational symmetry = 360 ÷ Angle of rotational symmetry. Therefore, the order of rotational symmetry = 360° ÷ 60° = 6

A) 60°
B) 120°
C) 90°
D) 180°
Explanation: The angle of rotational symmetry = 360° ÷ Order of rotational symmetry. Therefore, the angle of rotational symmetry = 360°/4 = 90°
Question 16: If the angle of rotational symmetry of a figure is 120°. then the order of rotational symmetry of the figure is __________.
A) 2
B) 3
C) 4
D) 6
Explanation: The order of rotational symmetry = 360 ÷ Angle of rotational symmetry. Therefore, the order of rotational symmetry = 360° ÷ 120° = 3

A) 6
B) 5
C) 4
D) 2
Explanation: The order of rotational symmetry of a hexagon is 6.
Question 18: When a figure is rotated about a point, it looks the same 3 times. What is the angle of rotational symmetry?
A) 60°
B) 90°
C) 120°
D) 180°
Explanation: The figure looks the same 3 times. Therefore, its order of rotational symmetry is 3. Angle of rotational symmetry = 360°/3 = 120°
Question 19: What is the order of rotational symmetry of a circle?
A) 10
B) infinite
C) 100
D) 1000
Explanation: The order of rotational symmetry = 360 ÷ Angle of rotational symmetry. The angle of rotational symmetry of a circle is 0°. Therefore, the order of rotational symmetry = 360° ÷ 0° = infinite
Question 20: What is the angle of rotational symmetry of a circle?
A) 10°
B) 40°
C) 0°
D) 90°
Explanation: The angle of rotational symmetry = 360° ÷ Order of rotational symmetry. The order of rotational symmetry of a circle is infinite. Therefore, the angle of rotational symmetry = 360°/infinite = 0°
