Question

the measure of one angle of paralleligram is 80 what areeaaure of remaning angle

Answer 1

Let the parallelogram be ABCD
Let angle A be 80°.
Therefore, angle C = angle A = 80°
(opposite angles of a parallelogram are equal)

Now, angle A + angle B = 180°
(sum of adjacent angles of a parallelogram are supplementary)
80°+B=180°
B=180°- 80°
B=100°

angle B = angle D = 100°
(opp. angles are equal)

Therefore, angle A=80° , angle B=100° , angle C=80° and angle D=100°.

Answer 2

Measure of one angle =80

name of parallelogram be ABCD

A =80 , A=C=80

C+B =180

80+B=180

B=180-80=80

B=D=80
