The units of measure used when defining a bolt circle hole list must all be of the same type for example. 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.

### Degreeradian circle in everyones experience it is usual to measure angles in degrees.

**60 degree angle in a circle**. Circles of latitude are often called parallels because they are parallel to each other. 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. 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.

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. This construction works by creating an equilateral triangle.

All in inches or all in millimetres. A point in any scale. We can measure angles in degrees.

This page shows how to construct draw a 60 degree angle with compass and straightedge or ruler. 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.

That is any two circles are always the same distance apart. All right angles are equal in measure. Degreed definition any of a series of steps or stages as in a process or course of action.

A locations position along a circle of latitude is given by its longitude. 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. Angles that have the same measure ie.

Glossary units of measure. 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. The term plane angle is sometimes used to distinguish angles in a plane from solid angles measured in space international standards organization 1982 p.

We use one of those angles to get the desired 60 degree result. A circle of latitude on earth is an abstract eastwest circle connecting all locations around earth ignoring elevation at a given latitude. There are 360 degrees in one full rotation one complete circle around.
