Reference Angle: Examples

Steps to Find Reference Angles The steps to find the reference angle of an angle are explained with an example. Let us find the reference angle of 480°. Step 1: Find the coterminal angle of the given angle that lies between 0° and 360°. The coterminal angle can be found either by adding or subtracting 360° from the… Continue reading Reference Angle: Examples

Degrees

Angles are measured in degrees. One revolution is divided into 360 equal parts and each part is called a degree. The angle subtended at the center of the circle after one complete rotation of the radius is 360°. The symbol for degrees is denoted by ‘°‘. Degrees is not an SI unit to measure angles… Continue reading Degrees

Radians

When we rotate the radius completely around the circle, it completes one rotation. The angle subtended at the center of the circle by the radius after one complete rotation is 2π radians. The angle in radians subtended by the radius at the center of the circle is the ratio of the length of the arc to the… Continue reading Radians

Radians to Degrees

Radians to degrees is a form of conversion used to convert the measurement of angles in geometry. To measure an angle, there are two different measuring systems. The two units used to measure an angle are radians and degrees. The unit radians is used mostly in the concept of trigonometry. The measure of angles can… Continue reading Radians to Degrees

Degrees and Radians

There are two commonly used units of measurement for angles. The more familiar unit of measurement is that of degrees and the other one is radians. In this lesson, we will learn how to measure angles in degrees, minutes and seconds how to convert an angle measured in degrees, minutes and seconds to decimal notation… Continue reading Degrees and Radians
