The measure of an angle of a parallelogram is 80 degree.Find its remaining angles.

The measure of its opposite angle is also 80 degree because opp. angles are equal .

The other two angles left are also equalso they can be named as x

the sum of all angles in parellelogram is 360 degree .then

80+x+80+x=360

160+2x=360

2x=360-160

2x=200

x=100

thus all the four angles are 80 , 80 , 100 and 100
