Question

The mesaure of a parallelogram is 80 degree what are yue measures of the remaining angles

Answer 1

two angles are of 100 degree and one of 80 degree

Answer 2

Answer:

$\angle \:D = 100 \degree$

Step-by-step explanation:

Let the parallelogram be ABCD and angle A be 80°

∠A + ∠B = 180° (alternate angles are supplementary)

80+ ∠B = 180

∠B = 180-80 = 100

∠C = ∠A (interior opposite angles of a parallelogram are equal)

∠C = 80°

∠ D = angle B (interior opposite angles of a parallelogram are equal)

∠ D = 100°

Measure of all angles are :

∠A=80°

∠B=100°

∠C=80°

∠D=100°
