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.
A parallelogram is a four-sided shape with opposite sides that are parallel. Because of the parallel lines, the opposites sides are equal in length. There are some unique properties of the angles inside parallelograms. First, the opposite angles are equal. Also, the adjacent angles are supplementary, which means they add up to 180 degrees. The perimeter of the parallelogram below, where the sides are 4, 4, 5 and 5, is 18. Example of a parallelogram When we have a specific type of quadrilateral like the one below, we can determine its area.
