sum of all the angle of a quad is 360degree.....hope helped

Answer 2

Explanation: We have seen in the Triangle Sum Conjecture that the sum of the angles in any triangle is 180degrees. The Quadrilateral Sum Conjecture tells us the sum of the angles in any convex quadrilateral is 360 degrees. Remember that a polygon is convex if each of its interior angles is less that 180 degree.
