Example Question #13 : How To Find An Angle In A Parallelogram
Using the parallelogram above, find the sum of angles  and Â
Not enough information is provided to find an answer.Â
A parallelogram must have equivalent opposite interior angles. Additionally, the sum of all four interior angles must equal  degrees.
Also, the adjacent interior angles must be supplementary angles (sum of  degrees).
Since, angles  and  are adjacent to each other they must be supplementary angles.
Thus, the sum of these two angles must equal  degrees.Â
