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.
