Question

the measure of one angle of parellogram is 80 degree what are the measure of reaming angle​

Answer 1

Answer:

in a llgm sum of all sides is 360 degree

angle 1+2+3+4=360

80 +2+3+4=360

and in llgm opposite angle are equal

so we can write angle 1=angle2

and angle 3=angle 4

80+80+angle3=360

160+angle 3=360

angle 3 =360-160

angle3=200

angle 4 =100 and angle 3=100
