60 degrees
Rotate 360 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.
180°
60 degrees. You find this by taking 360 and dividing by the total sides (6) which leaves you with the degrees of the exterior angles, this exterior angle is how little you can rotate any polygon for that matter.
reflect across the x-axis and then reflect again over the x-axis
