The solid angles help us have a view of an object in three dimensions.
it is same as surface and volume ! a plane angle is 2D and solid angle is 3D
A solid angle is 3-dimensional, a planar angle is 2-d.
It is a solid angle, or an angle in 3-d space.
Solid angle is vector quantity. BY WAHID BUX MAHAR
A solid angle, measured from a vertex, is the ratio between the area subtended by the angle at the vertex and the the square of the distance to the vertex. The unit of measurement is the stradian.
2π
A steradian.

solid angle is the ratio of the intercepted area dA of the spherical surface , described about the apex O as the centre ,to square of its radius r
a solid figure that has a right angle
A cuboid is a three dimensional solid: it is not an angle of any sort.
if alpha is the solid angle subtended by a cone and theta is the 2d projection angle of this solid angle...Then----(both alpha and theta are in radians then) cos(theta) = 1 - (alpha/2*pi)
