Question

find the measure of all the angels of a parallelogram ABCD if m angle D = 6o degree​

Answer 1

Answer:

We know that Opposite angle of the parallelogram are equal.

So, B=D=60 degree

and also adjacent angle are supplementary

So, A+B=180

A=180-60=120 degree

C=A=120 degree. [Opposite angle are equal ]

Hence, A=120 , B=60 , C=120 , D=60 degree(s)

Answer 2

Answer:

hope this helps u

Step-by-step explanation:

abcd is a parallelogram

given ∠d=60

in a parallelogram opposite angles are equal

∠b=∠d

∠b=60

in a parallelogram adjacent angle sum up to 180

∠b+∠a=180

60+∠a=180

∠a=120

in a parallelogram opposite angles are equal

∠a=∠c

∠c=120
