Question

ABCD is a parallelogram in which angle A =70 compute angleB ,angleC and angleD ?

Answer 1

Answer:

angle A + angle B = 180 degree

angle B = 180-70=110

opposite angle , angle B = angle C = 110 degree

then opposite angle , angle A = angle D = 70 degree

Answer 2

Explanation:angle A+angle B=180

angle B=180-70

angle B=110

angle C=angle A (vertical opposite angle)

angle C=70

angle D=angle B (vertical opposite angle)

angle D=110.
