The sum of interior angles of a quadrilateral is how many degrees?

Split the quadrilateral into two triangles by drawing a diagonal. Each triangle has interior angles totaling 180 degrees, so together they sum to 360 degrees. In general, a polygon with n sides has interior angles that sum to (n−2)×180 degrees; for four sides, that gives 360. The other numbers correspond to polygons with different numbers of sides (triangle 180, pentagon 540, hexagon 720).
