Question

2. Measure of one angle of a parallelogram is 100 degrees . Find the other three angles.

Answer 1

Step-by-step explanation:

If we have a parallelogram with one side as 100° so we know that opposite angles in a parallelogram are equal so,

angle A== angle C ==100°

Let angle B=angle D=x

Angle a + angleB+angle C+angle D=360°(A.S.P)

100+x+100+x=360

200+2x=360

2x=360-200

2x=160

x=80

angle B=angle D=80
