Question

ABCD is a parallelogram and A =80. find other angle of a parallelogram

Answer 1

Answer:

this so easy

Step-by-step explanation:

ok see

ABCD is parallelogram means parallel lines

so if AB II CD and AC is transversal so C = 180- 80 ( CO INT ANGLE)

C = 100

SO B= 100 ( opp angel)

A = 80 soo D = 80

that's it

hope it helps

Answer 2

ANSWER:-

In a parallelogram opposite angles are equal and opposite sides are parallel. thus two angles on the same side are supplementary therefore, in the parallelogram the angle opposite to the 80* will be 80*.

and the other two angles will be

=> 2x + 2(80°) = 360°

=> 2x = 360°- 160°

=> x = 200°/2 = 100°

The angles of parallelogram are:- 100,80,100,80
