Question

ABCD isa parallelogram in which one angle is 120 degree find the other three angles

Answer 1

Answer:

hiii

your answer is here !

Step-by-step explanation:

Hello Dear!!!

Here's your answer...

One angle is 120°

Sum of adjacent angles in a parallelogram is 180

Let,

The adjacent angle be x

x+120=180

x= 180-120

x=60°

Adjacent angle is 60°

Opposite angles are equal in a parallelogram

So...angles are 120,60,120,60

Answer 2

Step-by-step explanation:

Let angle A=120

angle A + angle B = 180 (sum of adjacent angles of parallelogram is 180)

then angle B =180-120=60

angle A=angle C. (opposite angles of parallelogram are equal)

then angle C=120

similarly angle D=60
