it is same as surface and volume ! a plane angle is 2D and solid angle is 3D
In a first angle projection, the object stands in between the observer and the plane of projection. In a third angle project, the object and the plane of projection is interchanged.
A horizontal angle is an angle between lines on a horizontal plane.
The difference is 270 degrees.
there is no difference

A horizontal angle is an angle between lines on a horizontal plane.
The difference between on and in is that if you're on a plane you're on the roof of the plane and if you're in a plane you're sitting inside it.
The difference is 270 degrees.

The angle between the orbital plane and equatorial plane of the earth (i.e., the angle of axial tilt) is about 23.4 degrees. This gives rise to the earth's seasons.

The angle of incidence is the angle between the incoming light ray and the normal of the surface.
The angle between the orbit planes of the Earth and the Moon is known as the inclination. It is approximately 5.1 degrees.
