Facts about right angles. Four right angles fit around a point. The way we define degrees, a full turn around a point is 360Â°, so the measure of each right angle is one fourth of that: 90Â°. In informal speech (not mathematics), right-angle corners are sometimes called square corners even though, as in the shapes above, there is nothing square about the shape.
An acute angle is any angle smaller than a right angle. A right angle is an angle that measures 90 degrees. A right angle forms part of a square, which is why it's often depicted by a square at the angle: So an acute angle is always smaller than the shown angle.
