angle
noun
/ˈæŋ.ɡəl/
|
- (geometry) A figure formed by two rays which start from a common point (a plane angle) or by three planes that intersect (a solid angle).
- (geometry) The measure of such a figure. In the case of a plane angle, this is the ratio (or proportional to the ratio) of the arc length to the radius of a section of a circle cut by the two rays, centered at their common point. In the case of a solid angle, this is the ratio of the surface area to the square of the radius of the section of a sphere.
