Question

In a parallelogram ABCD, angle D = 120 degree. Find the measurement of angle A.

Answer 1

Dear Student

Given : ABCD is a parallelogram and angle D =${120}^0$
Now
From the properties of parallelogram
angle A + angle D =${180}^0$
${120}^0$ + D = ${180}^0$
therefore D= ${180}^0$ -${120}^0$ = ${60}^0$
