For this measurement, consider the unit circle (a circle of radius 1) whose center is the vertex of the angle in question. ... Although the word "radian" was coined by Thomas Muir and/or James Thompson about 1870, mathematicians had been measuring angles that way for a long time. For instance, Leonhard Euler (1707-1783) in...

radius: distance from center of circle to any point on it. sector: is like a slice of pie (a circle wedge). tangent of circle: a line perpendicular to the radius that touches ONLY one point on the circle.

A method of measuring the radius of curvature of an object to be examined has a first procedure of projecting two pairs of light spots onto the object from different directions, a second procedure of obtaining by an imaging optical system the reflected images of the two pairs of light spots reflected by the ...

The radius of a circle is the distance from the center of a circle to any point on the circle. If you place two radii end-to-end in a circle, you would have the same length as one diameter. Thus, the diameter of a circle is twice as long as the radius.
