Question

By which angle measures can the square be rotated so it maps onto itself?

Select each correct answer.

45°
60°
90°
135°
180°
270°

Answer 1

90°, 180° and 270°

Step-by-step explanation:

Answer 2

The correct answers are:

90°, 180° and 270°

Step-by-step explanation:

Squares have rotational symmetry at 90°. This can be found by dividing the number of degrees in a circle, 360, by the number of sides, 4:

360/4 = 90

This means that at all multiples of 90, the square will rotate onto itself. This means that 90, 180 and 270 are all correct.
