#### What is a radian?

Here is a video about them. There is also more information below the video.

A radian is a unit of measuring angles just like a degree is. A radian is a distance on the circle’s circumference which is equal to 1 radius.

This means there are radians in one circle or that radians equals 360 degrees.

If radians equals 360 degrees that means that 1 degree equals divided by 360 radians or divided by 180 radians.

1 radian = degrees

1 degree = radians

This is a degrees and radians chart. If 1 degree = radians then 30 degrees equals 30 times that or radians. The same thing can be done to find the radian measure for other angles.
