Question

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

Answer 1

Answer:

in a parallelogram two opposite side are equal

Step-by-step explanation:

in a quadrilateral all side is 360

so one angle is 120 the opposite angle is also120

360=120+120

360=240

360-240=120

in this case we have conclude two more sides

so,2x=120

x=60

the parallelogram we have to give name is ABCD

A=120

B=60

C=120

D=60
