### Degreed definition any of a series of steps or stages as in a process or course of action.

**60 degree angle in a circle**. Angles that have the same measure ie. The units of measure used when defining a bolt circle hole list must all be of the same type for example. There are 360 degrees in one full rotation one complete circle around.

This page shows how to construct draw a 60 degree angle with compass and straightedge or ruler. That is any two circles are always the same distance apart. Probably because old calendars such as the persian calendar used 360 days for a year when they watched the stars they saw them revolve around the north star one degree per.

We learn early in childhood that there are 360 degrees in a circle that there are 90 degrees in a right angle and that the angle of an equilateral triangle contains 60 degrees. See the proof below for more details. Two angles which share terminal sides but differ in size by an integer multiple of a turn are called coterminal angles.

Glossary units of measure. The same magnitude are said to be equal or congruentan angle is defined by its measure and is not dependent upon the lengths of the sides of the angle eg. A circle of latitude on earth is an abstract eastwest circle connecting all locations around earth ignoring elevation at a given latitude.

All right angles are equal in measure. A point in any scale. Heres another calculator that you can use to check your work going from an angle measurement using a decimal number of degrees to the same angle measurement expressed in terms of degrees minutes and seconds.

We can measure angles in degrees. A locations position along a circle of latitude is given by its longitude. This construction works by creating an equilateral triangle.

We use one of those angles to get the desired 60 degree result. Recall that an equilateral triangle has all three interior angles 60 degrees. Printable step by step instructions for drawing a 60 degree angle with compass and straightedge or ruler.

Given two intersecting lines or line segments the amount of rotation about the point of intersection the vertex required to bring one into correspondence with the other is called the angle theta between them. Degreeradian circle in everyones experience it is usual to measure angles in degrees. The term plane angle is sometimes used to distinguish angles in a plane from solid angles measured in space international standards organization 1982 p.
