Question

in a parallelogram abcd the measure of angle is 120 find the measure of angle c and angle d​

Answer 1

Answer :

Angle C = 120° and angle D = 60°

Answer 2

Answer:

angle b = angle d = 120 degree, angle c = angle a = 60 degree

Step-by-step explanation:

Assuming angle b is 120 degrees,

Angle d is also 120 degree, since opposite angles are equal in a parallelogram

Sum of interior angles of a parallelogram= 360 degree

Angle a= Angle c = x {constant}, since they are opposite angles

Therefore,

a + b + c + d = 360

x + x + 120 + 120 = 360

2x + 120 + 120 = 360

2x + 240= 360

2x = 360-240

2x = 120

x = 120/2

x = 60 degrees

Angles a and c measure 60 degrees each
