Question

if one angle of a parallogram is 60 degrees, find the number of degrees in the remaining three angles.

Answer 1

Angle opposite the 60-degree angle is also 60 degrees.

The remaining two angles are 120 degrees.

Answer 2

Keep in mind, in a parallelogram,
1) Opposite angles are equal.
2) Consecutive angles are supplementary. So that if one angle is 60, the angle next to it, will be 120.
