Question

Hi guys

Please give me the ans of these question .

An exterior angle of a parellelogram is 120°. Find the angles of the parellelogram.

Answer 1

The angles of the parallelogram will be 60, 120, 60, 120.

Exterior angle+Interior angle=180(Sum of angles on a straight line=180)
120+x=180
x=180-120=60
Conjoint angles=180
x+y=180
60+y=180
y=180-60=120
Opposite angles off a parallelogram are equal
Therefore, the angles are 60, 120, 60, 120

Answer 2

√e=120°
then.
by the theorum exterior angle is equal to the sum of 2 interior angle
so ..two angles are
√b=60° and
√d=60°
whose sum is equal to one exterior angle
and we all know that the parallelogram have 360° angles and the two other angles are 120° and 120° angles because parallelogram have two equal pairs of angles


√a=120
√b=60
√c=120
√d=60

hope it helps
