Question

What is the sum of all interior angles of a convex quadrilateral ?

Answer 1

Answer:

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. In other words, the polygon is convex if it does not bend "inwards".
