supplimentary angles
A straight angle.
45 degrees. 45 degrees
In a parallelogram, opposite angles are equal in measure. Therefore, the angle opposite the 37-degree angle will also measure 37 degrees. The sum of the interior angles of any quadrilateral is always 360 degrees. Since opposite angles in a parallelogram are equal, the other two angles will also measure 37 degrees each.
90 degrees.

you measure the opposite side and then subtract it of 360 degrees.
