Question

The angles between North and West and South and East are ______.

Options

• complementary

• supplementary

• both are acute

• both are obtuse

Answer 1

The angles between North and West and South and East are supplementary.

Explanation:

The angle between North and West is 90^o, angle between South and East is 90^o as shown in the figure above. So, 90^o + 90^o = 180^o.

Then, the angles between North and West and South and East are supplementary.

When the sum of the measures of two angles is 180°, then the angles are called supplementary angles.
