Question

Niharika took two angles- ${130}^0$ and ${50}^0$ and tried to check whether they form a linear pair. She made the following picture. Can we say that these two angles do not form a linear pair ? If not , what is Niharika's mistake ?

Answer 1

A linear pair is a pair of adjacent, supplementary angles. Adjacent means next to each other, and Supplementary means that the measures of the two angles add up to equal ${180}^{\circ }$.

In the given figure, angles are not adjacent to each other means they don’t have any common arm.

So, we can say that given angles do not form a linear pair.
