One such jewel of mathematics is the ‘Linear Pair’ of angles. Linear Pain is a set of two angles that are adjacent to each other, formed by two intersecting lines, and the measure of straight angle should be 180 degrees. In our daily routine, we face several situations where the concept of Linear Pair of angles is applied. Even if we don’t notice, there are many things around us which form the part of Linear Pair.#N#The conditions of a Linear Pair angle are:
Why is it important to know the linear pair of angles?
Another reason to be thankful to the Linear Pair of angles is that it is involved in delivering justice; as the angles formed in a justice-balance-machine are nothing but the Linear Pair of angles.
Do linear pairs exist in real life?
Have a common vertex. Non-common side must make a straight line or sum of angles must be 180 degrees. We all might have thought that the Linear Pair have no existence in real life. It’s just a theoretical work. But, there are plenty of examples in our daily life, which suggests the involvement of Linear Pair of angles.

What is linear pair?
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 degrees.
How many degrees do two angles add to?
We know that the two angles form a linear pair. We also know that their measures add to equal 180 degrees. That means that we can add the two expressions and set it equal to 180 in order to solve.

What are the angles formed at O?
The angles which are formed at O are ∠ POB and ∠ POA. It is known that the angle between the two line segments AO and OB is 180° . therefore, the angles ∠ POB and ∠ POA add up to 180°.
What is a linear pair of angles?
Linear Pair Of Angles. Linear pair of angles are formed when two lines intersect each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°. Such angles are also known as supplementary angles.
What is a straight angle?
Explanation for Linear Pair of Angles. When the angle between the two lines is 180°, they form a straight angle. A straight angle is just another way to represent a straight line. A straight line can be visualized as a circle with an infinite radius. A line segment is any portion of a line which has two endpoints.
What is a line segment?
A line segment is any portion of a line which has two endpoints. Also, a portion of any line with only one endpoint is called a ray. A line segment with A and B as two endpoints is represented as . The figure shown below represents a line segment AB and the two arrows at the end indicate a line.

What are the two types of angles?
In geometry, there are two types of angles whose sum is 180 degrees. They are linear pairs of angles and supplementary angles. We often say that the linear pair of angles are supplementary, but do you know that these two types of angles are not the same? Let us understand the difference between supplementary angles and linear pair of angles through the table given below:
What is a linear pair of angles?
In geometry, a linear pair of angles is a pair of adjacent angles formed when two lines intersect each other. Adjacent angles are formed when two angles have a common vertex and a common arm but do not overlap. The linear pair of angles are always supplementary as they form on a straight line. In other words, the sum of two angles in a linear pair is always 180 degrees.
