Adjacent angles are known as a very common type of angle which would be having a very common arm and a common vertex but they will never overlap with each other. The angle which has been formulated whenever 2 Lines will be meeting at a common endpoint is the adjacent angles will be those that will be always placed next to each other. Two angles are always said to be the adjacent angles whenever they will be sharing a common side and common vertex without any kind of overlapping elements in the whole process.

The very basic definition of the adjacent angles will be that these will be the angles that will be placed next to each other in such a manner that they will be sharing a common vertex and a common side without any kind of overlapping element. Some of the most important examples of the adjacent angles are:

- Two pizza slices are placed next to each other
- Hands of the clock will be showing the minute, second and hours clocked in the whole process.
- People can very easily find out three adjacent angles in the steering wheel of the car as well.

Some of the most common properties of the adjacent angles have been significantly explained as follows:

- The adjacent angles will always be having a common arm
- They will always be sharing a common vertex
- They will always be making sure that there will be no chance of any kind of overlapping elements in the whole process
- The adjacent angles will be having a non-common arm on both sides of the common as well.
- There will be two adjacent angles which can be supplementary and complementary depending on the sum of the measures of the individual angles in the whole process.

It is very much important for people to indulge in proper identification of the adjacent angles in the whole thing so that there is no chance of any kind of hassle and everybody will be able to deal with the very basic properties very successfully. The adjacent angles will always be sharing a common side and common vertex and if any angle is satisfying two of these properties then it will be considered as an adjacent angle otherwise it will not be considered as the adjacent angle. For example, if any two angles are sharing a common vertex but they have an angle in between them then they will not be sharing a common side which very well justifies that they will not be categorised as adjacent angles in the whole process.

Some of the most important notes on this particular topic have been explained as follows:

- The adjacent angles are only possible whenever the sum of the angle will be formulated by two non-common arms and one common arm
- If a ray is standing on the straight line then the sum of adjacent angles will be formulated as 180°
- If the sum of 2 adjacent angles is 180° then they will be considered as a pair of linear pair as well. Linear pair angles are always supplementary because their sum is 180° but it is important for people to note down that all supplementary angles are not linear pairs and to formulate the linear pair people need to make sure that lines are intersecting with each other and are formulating the adjacent angles.
- If two adjacent angles are 180° in terms of sum then the non-common arms will always help in forming out a line.

Apart from all the above-mentioned points, it is also very much vital for people to depend upon platforms like **Cuemath** so that they have a good hold over the topics like **vertical angles** very successfully and easily.
