Angle conversion calculator will also calculate the equivalent angle in another unit. if you enter the angle in the form of a deg then convert rad and grad.

## What are Angles?

An angle is the figure formed by two planes, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles are typically represented by the symbol ɑ, β or θ, where ɑ is the initial letter in the Greek alphabet, β is the second letter and θ is the third. value an angle is generally in degrees (°), arcminutes (‘), radians, gradians and arcseconds (“). One degree is equivalent to sixty arcminutes and to three-sixty arcseconds.

◉ Any two lines in the plane that intersect and do not pass through the same point are called intersecting lines. A line is a special kind of plane figure called a line segment. A plane figure is a flat shape. A plane is a flat surface. A plane angle is formed when two lines intersect.

◉ Angles are also classified according to the size of the angles. An angle smaller than a 90 degrees angle is called an acute angle. An angle larger than a 90 degrees angle is an obtuse angle. An angle equal to a right angle is called a straight angle. An angle, not a right angle, is called an oblique angle.

## Units of angle?

Angle units are degrees (°), radian (rad), minute of arc (arcminute, arcmin’s), second of arc (arcsecond, arcsec), and gradians (grad or gon)
