Understanding the concept of angular, therefore, forces us to focus first on the idea of angle (which comes from Latin angŭlus, in turn derived from the Greek ankýlos which can be translated as "curved"). An angle is a geometric figure which is formed with two concurrent lines at a point; with two semi-planes that have their origin in the same line; or by three or more planes that intersect at a certain point.

By extension, it is also known as an angle at a corner or a corner. In a figurative sense, an angle is called point of view.

The adjective angular can be used to refer to what is linked to the angle.

The angular adjective

A square bracket angularMeanwhile, it is an orthographic sign that has multiple uses. It can appear in single or double format, depending on the case.

The notion in mechanics and astronomy

In the field of mechanics, we can find the expression angular velocity. It is a physical quantity that enables the expression of an angle drawn by the radius of an object that rotates around an axis in a time unit.

If we focus on the astronomy, we will find the idea of angular distance. This is how the angle that develops from the visuals to two stars that are located close to each other in the celestial sphere is mentioned.

In optics, an angle is a type of lens.

Angular in anatomy

The anatomy is another science that uses the word angular. This is what a bone that is located in the jaw of some animals, such as birds, reptiles, amphibians and certain fish.

The concept in optics

In the optics, the angular or wide angle it's a objective capable of offering coverage of a visual angle of between 70º and 180º.

On the other hand, the angular aperture is the largest angle of light rays that can enter a device to form a picture.
