90 degrees
An acute angle is an angle of less than 90°. A 90° angle is a right angle, the angle you find at two adjoining edges of a square. An angle smaller than a right angle is called an acute angle, while an angle larger than it is called and obtuse angle.

Each angle in a square is a right angle, or a 90 degree angle.
A circle has 360 degrees and a square has four 90 degree angles as does a rectangle.It's called complementary. A 90 degree angle is called supplementary.
