Question

one of the angles of a parallelogram is 80 degree find the measure of all the remaining three angles ​

Answer 1

Answer:

100,100,80

Step-by-step explanation:

the measure of the opposite angles of a parallelogram are always equal hence the second angle is also 80

now the sum of two adjacent angles is 180

let the third angle be x

then

x+80=180

x=100

then thefourth angle would also be 100
