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.
Since the sum of the interior angles of any triangle is 180Â° and there are two triangles in a quadrilateral, the sum of the angles for each quadrilateral is 360Â°. Specific Types of Quadrilaterals. Letâs start by examining the group of quadrilaterals that have two pairs of parallel sides. These quadrilaterals are called parallelograms They take a variety of shapes, but one classic example is shown below. Imagine extending the pairs of opposite sides.
