-- The sum of the four exterior angles is 360 degrees. -- The sum of the four interior angles is also 360 degrees. -- So the sum of all the interior and exterior angles is 720 degrees.
The sum of the interior angles of a quadrilateral are 360 degrees
The interior angles of all quadrilaterals sum to 360 degrees. Since a parallelogram is a quadrilateral, its interior angles must sum to 360 degrees.
Sum of the exterior angles is 360 degrees. So the sum of the interior angles must be 3*360 = 1080 degrees.
The sum of the four interior angles of a trapezoid is 360 degrees.

The sum of the interior angles of a parallelogram is 360 degrees.
-- The sum of exterior angles of any polygon is 360 degrees.-- The sum of interior angles of any quadrilateral, no matter what shape, is 360 degrees.-- 360 + 360 = 720 degrees.
The sum of the interior angles of a rectangle is 360 degrees.
The sum of the 4 interior angles of any quadrilateral add up to 360 degrees.
