Question

What is the minimum number of degrees that a square can be rotated before it carries onto itself?

Answer 1

90

Explanation:

Answer 2

Since a square is a parallelogram with 4 equal sides, therefore it only requires a 90 degree rotation before it carries onto itself. A full rotation is equivalent to 360 degrees, since it has 4 equal sides,

Minimum degrees = 360 degrees / 4

Minimum degrees = 90 degrees
