Linear projection-a time line
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.

That's true of the Mercator projection, among others.
thrid angle projection is officially used in Australia, for a fact, not lying!!
non linear
Polar projections are often made in what is called the Azimuthal Equidistant Projection. The projection would be made tangent at the north pole, or at the south pole. These projections allow you to make linear measurements from the pole to any point on earth. These measurements are the shortest distances from the pole to the points and can be directly compared to one another. A polar projection shows the poles; I learned it in my science class.
what similarity about the mercator projection and the robinson projection?
the angkle of projection is an angle and the projection
A meatus is an opening; therefor, it's a depression, not a projection.
Robinson projection
Parallel projection does not produces realistic views whereas perspective projection produces realistic viewin parallel projection lines of projection are parallel whereas in perspective projection lines are not parallel and the point where these lines meets is called ceter of projection in case of perspective projection

A projection formula shows a three-dimensional (3-D) structure in a two-dimensional (2-D) form. It portrays the structure of the compound in a plane that consists of symbols that represent atoms.
