A parallelogram that has one angle that measures 166.5°. The other three angles are 166.5°, 13.5°, and 13.5°.
What is a parallelogram?
That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
We have been given a parallelogram that has one angle that measures 166.5°.
we know that the opposite angle of the parallelogram is the same.
So, the second angle is also 166.5°.
Now, one of the properties of parallelogram states that the adjacent angles are supplementary.
166.5° + x = 180
x = 180 - 166.5°
x = 13.5°
similarly, the opposite angle of the parallelogram is the same.
So, the fourth angle is also 13.5°.
