If an angle of a parallelogram is two-third of its adjacent angle, then the smallest angle of the parallelogram is 72°. Adjacent angles exhibit a common side and a corner point.
Adjacent angles exhibit a common side and a corner point, although they do not overlap.
A parallelogram can be defined as a simple type of quadrilateral having two pairs of parallel sides.
A rectangle can in turn be defined as a parallelogram having four right angles (90°), thereby all rectangles represent quadrilaterals.
The sum of the adjacent angles of a parallelogram is equal to 180°.
In this case, we have that the sum of adjacent angles >> X + 2/3 X = 180° >> X = 108° >> 2/3 X = 72°
