No, a square cannot rotate onto itself at 90 degrees. When a square is rotated by 90 degrees, its orientation changes, and it does not match its original position. However, it can be rotated by 90 degrees and still appear the same due to its symmetrical properties, but it is not the same configuration as its starting point.

Yes
A square.
It is 180 degrees.

A square can be rotated onto itself at specific angles of 0 degrees, 90 degrees, 180 degrees, and 270 degrees. This means it has four positions of symmetry through rotation. Therefore, a square can be rotated by any multiple of 90 degrees to map onto itself.
The smallest number of degrees needed to rotate a regular pentagon around its center onto itself is 72 degrees. This is because a regular pentagon has five sides, and a full rotation is 360 degrees. Dividing 360 by 5 gives you the angle of rotation that maps the pentagon onto itself, which is 72 degrees.
With 4 equally spaced blades on a fan, you can rotate the fan onto itself with a minimum of 90 degrees. Each blade will align with the next blade at a quarter turn, which corresponds to 90 degrees.
