Question

If one angle of a parallelogram is 70 o , find the other angles.

Answer 1

In a parallelogram, the adjacent angles are co-interior and the opposite angles are equal. So if one angle is 70°, the angle opposite to this angle is 70°. And the angle adjacent to this angle is supplementary to it. Therefore, the angles of the parallelogram are 70°, 110°, 70° & 110°.
