Learn and know the how to explain **linear pair definition** in Geometry. We also know the real life example for linear pair that we observe in our daily life.

Before learning the **definition**, we will understand the **meaning of linear pair**. In linear pair we have two words. If we see them separately linear means straight line and pair means two. As we understood the meaning, now I will give the **definition of linear pair** and also some examples.

**Linear pair definition in math as follows:**

If the sum of the two adjacent angles is supplementary or it is equals to 180° then we say the two adjacent angles forms a **linear pair**.

If the non common arms of two adjacent angles are in opposite direction then also we say the two adjacent angles forms a **linear pair**.

Example:

In the diagram, we have two adjacent angles i.e. ∠SPQ and ∠SPR . The non common arms of these two angles i.e. PQ and PR forms a straight line and sum of the two angles is supplementary. So the two angles ∠SPQ and ∠SPR forms a linear pair.

**Linear pair example in real life:**

**Pen stand** is one of the examples in real life for linear pair. Still if you come across any real life example let me know.

Hope **linear pair definition** is clear.

The good thing about this blog is that I can relate to it myself. It is surely going to help me in my future endeavors. Keep up the good work.
