Robert drew a parallelogram with two 55-degree angles.What are the measures of the other two angles?
The sum of the angles = 360
paralleograms have pairs of equal angles.
You have 110 degrees so far.
Now can you find the other two angles?
(360 - 110)/2 = 125
the measures of one of the angle of parallelogram is 60. Find the measures of opposite angles
