90 degrees. Exterior angle of any regular n-sided polygon is 360/n degrees
Each exterior angle of a square is 90 degrees and a square is a regular 4 sided quadrilateral
An exterior angle is on the outside of a shape. For example, the internal angle of a corner of a square is 90 degrees. 360 degrees less 90 degrees equals 270 degrees. Therefore, the exterior angle of a right-angle is 270 degrees. Search Google with "exterior angle" for more info.
