Question

in a parallelogram ABCD,if B=135 degree, determine the measures of its other angle

Answer 1

heya

if b=135degree, then d= 135 degree as opposite angles of a parallelogram are equal

also angle c=180-135 = 45 degree as adjacent angles of parallelogram are supplementary.

and a= c= 45 degree

Answer 2

Angle D =135 and angle A and C are equal to 45
