Question

Definition of plane angle and solid angle

Answer 1

A solid angle is a 3D angular volume that is defined analogously to the definition of a plane angle in two dimensions. ... A plane angle, θ, made up of the lines from two points meeting at a vertex, is defined by the arc length of a circle subtended by the lines and by the radius of that circle, as shown below.
