Respuesta :

The correct answers are:

90°, 180° and 270°

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.

Answer:

90°, 180° and 270°
