Question

One angle of a parallelogram measures 60°. What are the measures of the other three angles in the parallelogram?

List answers from lowest to highest.

Answer 1

60 degrees

120 degrees

120 degrees

Explanation:

A parallelogram is quadrilateral that has two pairs of parallel sides. The opposite sides equal in length

Area = base x height

Sum of angels in a parallelogram is 360 degrees. Opposite angles are equal

If one angle measures 60 degree, the opposite angle would measure 60 degree

Angles remaining = 360 - 60 - 60 = 240

since opposite angles would be equal, each angle = 240 / 2 = 120
