# What are the things that you need to know about the concept of supplementary angles?

Supplementary angles make sure that there will be a pair of two angles that will be forming out a straight angle or 180° whenever they will be put together. These two angles are known as supplements of each other and measuring angles and finding the angles is considered to be one of the most important activities to be carried out by people in the world of mathematics. So, in this particular case, people need to be very much clear about the basic concepts so that exploring the world of **supplementary angles** becomes easy and there is no chance of any kind of problem throughout the process.

Two angles are always said to be supplementary whenever they will be adding up to 180° and supplementary angles will be forming out a straight angle whenever they will be put together. So, if angle one and angle two are supplementary then angle 1+ angle 2 will come out to be 180°.

It is also very much important for people to be clear about the bifurcation of supplementary angles which have been explained as follows:

- Adjacent supplementary angles are the ones that will be having a common vertex and common arm and will also add up to 180° when brought together.
- Two supplementary angles are not adjacent or said to be the non-adjacent supplementary angles and they will also be adding up to 180°.

It is also vital for kids to be clear about the basic difference between the supplementary and complementary angles and they have been explained as follows:

- Two angles are said to be complementary if they will be adding up to 90° and on the other hand, two angles are said to be supplementary if they will be adding up to 180°.
- The process of finding out the complementary of angle X will be 90° – X and on the other hand, the process of finding out the supplement of angle X will be 180° – X.

Following is the short trick which people need to know so that they can understand the basic difference between both of these angles:

- Alphabet S will always stand for supplementary angles as well as for straight angles and from this particular point people can remember that two supplementary angles whenever to put together will be forming out first-rate angle.
- On the other hand alphabet C will be standing out for the complimentary as well as four corners and people can significantly remember that complementary angles wherever put together will be forming outer corner or rectangle in the whole process.

** How can you very easily find out the supplement of angle?**

Whenever the sum of two pairs of angles will be equal to 180° then people can call that particular pair of angles as supplements of each other and further being clear about the categorisation of finding out the supplement of each other it is very much a model for people to be clear about subtracting that particular value from 180°. So, the supplement of X degree will be 180 minus X degree and in this particular case suppose the value of X is 77 then subtracting it from 180° will come out to be 103° so that there is no chance of any kind of mistake and everything will be perfectly carried out.

Hence, depending upon the platforms like **Cuemath** is the best possible decision which people can make in their life so that they have a good command over the subject of mathematics very successfully and are further very much capable of deal with the **corresponding angles** without any kind of problem.
