# What are the very basic features that you need to know about the concept of angles?

In the world of mathematics, people need to be very much clear about diverse concepts so that they can have a good command of the subject and can score well very easily in this particular area. Depending upon the concept of types of angles is very much important so that people can indulge in the accurate measurement of the things and there is no chance of any kind of mistake throughout the process.

Angles are always formulated with two line segments that will be intersecting each other at a particular point and the measure of the opening between these two lines will be known as the angle. It is usually measured into degrees and is becoming one of the most important components of human life. Engineers and architects are using angles for designing roads, buildings, sports facilities and several other kinds of things since day one.

It is very much important for people to be clear about different types of angles and their properties and some of the basic categories are explained as follows:

- An acute angle is the angle whose measure is less than 90° but greater than 0°
- The right angle is the angle which will be exactly measuring equal to 90° and will also be formulating the shape of the alphabet L.
- Whenever the measurement of the angle will be less than 180° but greater than 90° it will be known as an obtuse angle.
- The angle formulated by the straight line will be known as a straight angle and it will be half of the whole turn of the circle. The measure of the straight angle will be 180°.
- A reflex angle is the angle whose measure is greater than 180° but less than 360°
- Whenever the measurement of angle will be equal to 360° it will be a complete angle.
- The angle which has been measured by counterclockwise or anticlockwise direction will be known as positive angle and from the origin, it will be drawn on the + X, +Y plane so that formulating of the positive angle can be carried out very easily.
- The negative angle is the one that will be measured into the clockwise direction from the base and origin this will be formulated towards the – X, – Y plane which will help in formulating a negative angle.

People need to be very much clear about the process of measuring the angle in the whole area and for this purpose, they need to be clear about the utilisation of protractors and other associated equipment in the world of mathematics. The steps are explained as:

- First of all, people need to align the protractor on the ray and start reading from the 0° mark on the bottom right of the protractor.
- After this people need to be clear about the number on the protractor which will be coinciding with the second line so that measurement of the angle can be carried out very easily and everybody will be having a good command over the lower arc.
- The utilisation of the protractor is considered to be the easiest possible way of ensuring that everybody will be able to measure the angles very successfully and apart from this people also need to be very much clear about the construction of angles so that there is no chance of any kind of mistake in the world of mathematics.

Hence, depending upon platforms like **Cuemath** is the best possible decision which people can make so that they are always on the right track of dealing with things very successfully and are very much capable of having a good command over the topic of **angles** in mathematics.
