The sum of the angles of a quadrilateral is 360 °. In a parallelogram, the sum of the angles adjacent to one side is 180 °. Therefore, we find the second angle: 180 – 60 = 120 °.
In the figure given to us, there are two pairs of identical angles, so the other angles are equal to 60 and 120 °.
Answer: 60, 120, 60, 120.
