Question

Measure of one angle of a parallalogram is 80 degree. find the other three angles .​

Answer 1

Answer:

The other 3 angles are 80°, 100° & 100°.

Step-by-step explanation:

Opposite angles of a parallelogram are equal, so, the opposite angle to the given angle is also 80°.

Similarly, the adjacent angles of a parallelogram have a sum of 180°. So, the angles adjacent to these two angles would be equal to 100°.

Thus, the other 3 angles are 80°, 100° & 100°.

Hope this helps.....

Answer 2

Answer:

The other three angles are 80°,100°,100°

Step-by-step explanation:

Hi mate Here is your answer

Let angle A=80°

A angle=80°

As we know adjacent sides of a parallelogram is 180°

Let the third angle be 'B'

80°+B=180°

B=180°-80°

B=100°

So,Angle A=80°

    Angle B=100°

    Angle c =?

    Angle D =?

And we know that opposite sides of a parallelogram is equal

 So,Angle B=Angle D

      Angle A=Angle C

      =100°=100°

      =80°=80°

Hope its clear....................
