Question

In a parallelogram ABCD if B = 80°, then find all other angles. ​

Answer 1

Answer:

Hence, ∠A= 80°, ∠B= 100°, ∠C= 80°, ∠D= 100° are the required angles of a parallelogram.

Step-by-step explanation:

ABCD is a parallelogram

∠c= 80°

The sum of adjacent angles of a parallelogram iis 180°

∠d= 180°- 80°= 100°

As we know opposite angles of a parallelogram are equal

Therefore

∠A= 80°

∠B= 100°

Hence, ∠A= 80°, ∠B= 100°, ∠C= 80°, ∠D= 100° are the required angles of a parallelogram.
