The sum of the exterior angles of a polygon equals 360.Quadrilateral has 4 exterior angles.360/4=90 for a regular quadrilateral.
1080 degrees (an average of 270 degrees, times the four angles).
The sum of all four interior angles in a quadrilateral must be 360, so the answer would be: 360 - 54 - 25 - 99 = 182
80 The angles in a quadrilateral add up to 360 degrees. So if 3 angles = 280 the fourth angle is 360-280 = 80
A kite is a quadrilateral so the sum of its interior angles is 360 degrees.
