Angle Unit Conversion Calculators
Angle is the space within two lines or three or more planes diverging from a common point, or within two planes diverging from a common line, according to Dictionary.com. Put another way, angle is the amount that one line or plane is turned from another.
Angles are used in geometry and trigonometry, geography and mapping, and construction, so understanding how to work with angles can be very important. A protractor is a common tool to help calculate angle between two lines.
Two common measures of angle are degrees and radians. A full circle consists of 360 degrees, meaning a line is 360 degrees from itself, which is 2π in radians. Angles are measured using a protractor, learn how to use a protractor or download a printable protractor to use to measure an angle for your project.
