Question

Measure of one of the angles of a parallelogram is 70˚. What is the measure of
its adjacent angle?

Answer 1

Step-by-step explanation:

opposite angles of a parallelogram are equal, so 1st angle will be 70° . And we know that adjacent angles of a parallelogram are supplementary (lines are parallel): so 2nd angle will be 110°. By this, all angles will be : 70° , 110°, 70° , 110 °.

Answer 2

Answer:

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°.
