Question

parallelogram ABCD if a equal to 65 degree find Angle B angle C and angle d ​

Answer 1

Step-by-step explanation:

A=65" therefore it's opposite angle which is C=65"

B=D(rule of parallelogram)as they are opposite angles

Let BandDbe x

x+x+A+B=360"(sum of all sides of a polygon)

2x+65+65=360"

2x+130=360"

X=230/2=115"

Answer-

A=65"

B=115"

C=65"

D=115"

Answer 2

Given - Measure of Angle A.

Find - Angle B, Angle C and Angle D

Solution - Angle A and Angle C is 65° and Angle B and Angle D is 115°.

In the parallelogram, two opposite angles are equal. Moreover, the sum of two neighbouring angles is 180°. Using given fact to find the remaining angles.

So, angle A will be equal to angle C..

Hence, Angle A = Angle C = 65°

Now, Angle A + Angle B = 180°

Angle B = 180° - Angle B

Angle B = 180° - 65°

Angle B = 115°

Angle B will be equal to Angle D.

Hence, Angle B = Angle D = 115°

Therefore, Angle A and Angle C is 65° and Angle B and Angle D is 115°.
