#LINEAR PAIR POSTULATE DEFINITION GEOMETRY SERIES#

Postulates like the linear pair postulate can be used in geometric proofs and mentioned in the justification section of the proof.

#LINEAR PAIR POSTULATE DEFINITION GEOMETRY SERIES#

The proof traces the series of facts, deductions and logic that support the final conclusion. In geometry, a proof is an argument that confirms or disproves a statement. It is possible to prove the statement “If two lines intersect, then they intersect in exactly one point.” Both postulates and theorems can be used to prove statements related to geometry. A theorem is a true statement that one can prove. For example, mathematicians believe the statement “through any two points there is exactly one line” despite the fact that it is not proven. Postulates are statements that have not been proven but are assumed to be true. The fifth postulate remains unproven despite several attempts over the years to prove it. Another asserts that all right angles are congruent. The second states that one can extend a straight line continuously. The first postulate states that it’s possible to draw a straight line between any two points. There are five geometric postulates explained in the book. His book, “Elements,” details 465 theorems and proofs that created the foundation of geometry as it’s studied today. So, the next time you see your mother working in the kitchen and chopping vegetables to make delicious dishes for you, don’t forget to notice the Linear Pair of angles formed on the chopping board.The Greek mathematician Euclid is recognized as the father of geometry because of the contributions he made to the field. You would be surprised to know that the Linear Pair of angles is also formed on the chopping board. Whenever you go for a drive, don’t forget to notice the Linear Pair of angles formed at the T-junction. Justice BalanceĪnother 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. The angles P and Q qualify all the conditions to be considered as a Linear Pair. Electric PoleĪn electric pole is also a real-life example of Linear Pair. ScissorsĪ pair of scissors is a classic example of Linear Pair of angles, where the flanks of scissors, which are adjacent to each other and have common vertex O, form an angle of 180 degrees. So, next time when you go to a pizza party don’t forget to salute the Linear Pair of angles. But, if we see the intersections of pizza, we would notice the presence of Linear Pair angles. Generally, no one would think about stuff like mathematics while enjoying pizza with friends. Here also, the angle A and B formed by the hands of the clock are adjacent to each other, have a common vertex, and the sum of both the angles is equal to 180 degrees. Here, the ‘angle A’ formed by placing the ladder against the wall is adjacent to ‘angle B.’ Both the angles formed have a common vertex and the sum equal to 180 degrees. Ladder placed against the wallĪ ladder placed against the wall is a real-life example of Linear Pair. So, let’s discuss some real-life examples of linear pair in detail. But, there are plenty of examples in our daily life, which suggests the involvement of Linear Pair of angles. We all might have thought that the Linear Pair have no existence in real life.

Non-common side must make a straight line or sum of angles must be 180 degrees.

The conditions of a Linear Pair angle are: Even if we don’t notice, there are many things around us which form the part of Linear Pair.

In our daily routine, we face several situations where the concept of Linear Pair of angles is applied. 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. One such jewel of mathematics is the ‘Linear Pair’ of angles.

Although mathematics might be considered one of the boredom subjects to many, but you would get amazed to know that it has many interesting concepts to experience in our daily life.
