Question

ABCD is a parallelogram in which one angle is 120°.Find the other three angles​

Answer 1

Answer:

120,120,60,60.

Step-by-step explanation:

According to the property of parallelogram the

opposite angles are equal

so the opposite angle of 120 degrees angle is also 120 degrees

According to the property of parallelogram the sum of two

adjacent angles is180 Degrees

let the other angle be X and we know the other angle that is 120 Degrees

120 + X = 180

         X =180-120

         X= 60

So therefore ,the angles of the parallelogram are 120,120,60,60.
