Question

in a paralellogram ABCD ,if angle a = 10 degree find angle b , angle c and angle d​

Answer 1

Step-by-step explanation:

ABCD is a parallelogram so its opposite angles are equal.

=angle A=angle C = 10 degree.

ALSO, the adjacent angles of parallelogram are supplementary.

angle A + angle B = 180 degree

10+angle B = 180degree

angle B = 180-10

angle B = 170 Degree.

.

angleA = 10 degree

angleB = 170 degree

angleC = 10 degree

angleD = 170 degree
