As we know the sum of two adjacent angles is 180 and forms a linear pair but if there are three angles and sum is 180 could it be linear pair or not?
If the sum of two adjacent angles is 180°, then the non-common arms of the angles form a line.
Answer: The sum of two adjacent angles is 180 and forms a linear pair but if there are three angles and sum is 180 then that is necesssarily not a linear pair. Such angles are called supplementary angles.
Let's understand in detail.
We can have three angles that are supplementary, but not necessarily adjacent.
So, they are supplementary angles but not necessarily a linear pair as they don't always form a straight line.
For example, angles in any triangle sum up to 180° but they are not a linear pair.
Thus, angles that add up to 180° do not always form a linear pair.
