Question 929601: john is drawing a parallelogram.one angle measures 120.what are the measures of the other three angles? Answer by LinnW(1048) (Show Source):
You can put this solution on YOUR website! The total of the four angles is 360
The angle opposite the angle which is 120 is also 120
The other opposite angles are equal so we can describe by
120 + 120 + 2x = 360
240 + 2x = 360
add -240 to each side
2x = 120
x = 60
So the angles are 120 60 120 60
