Question

can a quadrilateral ABCD be a parallelogram if iii) angle b=105 ,angle d=75​

Answer 1

Answer:

yes it can be quadrilateral

since the sum of its opposite side is 180°

i.e 105+75=180

Answer 2

Step-by-step explanation:

it it can be a quadrilateral that is parallelogram if if the sum of Angle B and A is 180 degree according to the property of parallel lines

Angle B and D are opposite angles

and opposite angles of a parallelogram are equal as all all opposite angles are equal and

a and B are supplementary

angles

• hence if angle a is equal to 105 degree then it can be a parallelogram

1. the given question receives an answer no as
2. d and b are not equal
