Question

the measure of one of the angle of a parallelogram is 60 find the measure of opposite angle​

Answer 1

Answer:

let ABCD be the parallelogram.

let ∠A=60 degrees Therefore ∠C=60 [in a parallelogram opposite angles equal]

∠A+∠B=180 degrees[sum of the adjacent angles]

∠B=180–60=120 degrees

∠B and ∠D are opposite angles .Therefore ∠D=120 degrees

Answer: ∠A=∠C=60 degrees

∠B=∠D=120 degrees
