WebJan 11, 2024 · A circle measures 360 degrees, or 2\pi 2π radians, whereas one radian equals 180 degrees. So degrees and radians are related by the following equations: 360°=2\pi radians 360° = 2πradians 180°=\pi radians 180° = πradians The relationship between radians and degrees allows us to convert to one another with simple formulas. WebJul 12, 2024 · Example 5.2. 1. Give the degree measure of the angle shown on the circle. The vertical and horizontal lines divide the circle into quarters. Since one full rotation is 360 degrees= 360 ∘, each quarter rotation is 360/4 = 90 ∘ or 90 degrees.

WebDegrees Degree is the unit of measure of an angle and is measured by using the geometric tool - a protractor. A degree is denoted by the symbol '°'. A circle completely rotates at a 360° and a degree is a part of that 360° rotation as it is divided into 360 equal parts. The different angles with different degrees are 30°, 45°, 90°, and so on.
