What is the smallest angle of rotational symmetry for a square?

O 45°

O 90°

O 180°

O 360°

Answer: 90°

Step-by-step explanation:

Rotational symmetry, also referred to as the radial symmetry is the property that a shape has when the shape looks identical after some rotation due to a partial turn.

A square has 4 right angles and a right angle is 90°. 4 right angles will be equal to 90° * 4 = 360°. The order for rotation of the square is 4. Therefore, we will have:

= 360° : 4

= 90°

Therefore, the angle of its rotational symmetry will be:

90°, 180°, 270°, 360°

The smallest angle of rotational symmetry for the square will be 90°
