Answer:
The sum of the exterior angles of a quadrilateral is 360 degrees. This is because the exterior angle of a polygon is supplementary to the interior angle (the angle formed by two adjacent sides). The sum of the interior angles in a quadrilateral is 360 degrees (180 x 2) and since the exterior angles are supplementary to the interior angles, the sum of the exterior angles is also 360 degrees.
