Question

In a parallelogram abcd , angle A =80°,find the measures of the remaining angles

Answer 1

Answer:

∠C=80°

∠B=100°

∠D=100°

Step-by-step explanation:

∠B=∠D & ∠A=∠C.............(opposite angles of a prallelogram)

Answer 2

Answer: ∠A= 80°, ∠B= 100°, ∠C= 80°, ∠D= 100°

Step-by-step explanation:

ABCD is a parallelogram

∠A= 80°

The sum of adjacent angles of a parallelogram iis 180°

∠B= 180°- 80°= 100°

As we know opposite angles of a parallelogram are equal

Therefore

∠C= 80°

∠D= 100°

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