Definition
A solid angle described by a smooth curve is a solid angle whose closed plane curve through which the half-lines pass is a smooth curve.
Hence the solid angle so defined is the nappe of a cone.
Vertex of Solid Angle
The common point through which pass the copunctal half-lines describing a solid angle is known as the vertex of that solid angle.
