Question

what are the different between plane angle and solid angle​

Answer 1

Answer:

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

Answer 2

Answer:

Solid Angle. ... 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. The dimensionless unit of plane angle is the radian, with 2π radians in a full circle.

plane angle : It usually refers to an angle in 2 dimensional figure like square, triangle, circle etc .

solid angle: It refers to an angle in 3 dimensional figure like cube,cuboid,sphere etc.
