Question

What is the minimum angle in degrees that any rectangle that is not a square should be rotated about its Center so that the rectangle maps onto itself?

Answer 1

The minimum angle that any rectangle (that is not a square) should be rotated about its center so that it maps onto itself is 90 degrees.

Step-by-step explanation:

In order for a rectangle to map onto itself, it must be rotated by a multiple of 90 degrees. This is because a rectangle has four right angles, so any rotation that is a multiple of 90 degrees will preserve the angles and the shape of the rectangle.

Therefore, the minimum angle in degrees that any rectangle (that is not a square) should be rotated about its center so that it maps onto itself is 90 degrees.
