उत्तर
The angles between North and West and South and East are supplementary.
Explanation:
The angle between North and West is 90o, angle between South and East is 90o as shown in the figure above. So, 90o + 90o = 180o.
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.
