Each minute is further divided into 60 equal parts called seconds, and, for instance, 2 degrees 5 minutes 30 seconds is written 2° 5' 30". So seven and a half degrees can be called 7 degrees and 30 minutes, written 7° 30'. Each degree is divided into 60 equal parts called minutes. For the time being, we’ll only consider angles between 0° and 360°, but later, in the section on trigonometric functions, we’ll consider angles greater than 360° and negative angles.ĭegrees may be further divided into minutes and seconds, but that division is not as universal as it used to be. A circle is divided into 360 equal degrees, so that a right angle is 90°. The more familiar unit of measurement is that of degrees. ![]() There are two commonly used units of measurement for angles.
