Question

ABCD is parallelogram in which ang A=70degree.compute ANGLE B,C,D.

Answer 1

angle B=110 degrees
angle C=70 degrees
angle D=110 degrees

Answer 2

ang A= ang C( opp. angles of a llgm are eq.)

angC= 70 degree

now angA+ angB = 180( adj. angles of a llgm are supply.)

angB=180 -70

       =110 dgree

again angB = angD ( opp. angles of a llgm are eq.)

ang D= 110 degree.
