Question

in a parellogram abcd if angel b = 65'what is the masure of angel​

Answer 1

Answer:

Let ABCD be a parallelogram in which ∠A=65

.

Since AD∥BC we can treat AB as a transversal. So,

∠A+∠B=180 65

+∠B=180 ∠B=180

−65

∠B=115

Since the opposite angles of a parallelogram are equal, we have

∠C=∠A=65

and ∠D=∠B=115

Hence, ∠B=115

,∠C=65 and ∠D=115
