solid angle

n.
An angle having a value equal to the area on a sphere subtended by a surface, divided by the square of the radius of that sphere. Solid angles are measured in steradians.

solid angle

n
(Mathematics) a geometric surface consisting of lines originating from a common point (the vertex) and passing through a closed curve or polygon: measured in steradians
