The same as the sum of angles of any quadrilateral. The sum of the angles only depends on the number of angles. If you want to visualize the sum of angles of a parallelogram, just draw one out and notice that there are two pairs of complementary angles, so the sum of the angles must be 360â.
Interior angles of a parallelogram. Try this Drag the orange dots on each vertex to reshape the parallelogram. Notice the behavior of the four interior angles. In any polygon, the interior angles have certain properties. See Interior angles of a polygon. A parallelogram however has some additional properties. If you start at any angle, and go around the parallelogram in either direction, each pair of angles you encounter always are supplementary - they add to 180Â°.
