Sum of interior angles equals 360°. A diagonal can be drawn from vertex A above dividing the quadrilateral into two triangles, ABC and ADC. Since the sum of the interior angles of a triangle is 180°, the sum of the interior angles for the quadrilateral is 2×180° = 360°. Special quadrilaterals. Quadrilaterals are widely studied in geometry.
