In a parallelogram, one angle is 70°. What are the measures of the other three angles?
70°, 110°, 110°
In a parallelogram, opposite angles are equal and adjacent angles are supplementary (sum to 180°).
Given one angle is 70°, the opposite angle is also 70°, and each adjacent angle is \(180-70=110\)°.
So the four angles are 70°, 110°, 70°, 110° — the other three being 70°, 110° and 110°.
Hence, the other three angles measure 70°, 110° and 110°.
