First angle projection is the one in which the object is placed in the first quadrant and views are projected on the planes. Refer this link for illustration and symbol http://www.technologystudent.com/designpro/ortho1.htm

the angkle of projection is an angle and the projection
they are fools
The range of projectile is maximum when the angle of projection is 45 Degrees.
I think it is just called the right angle symbol

first angle projection and third angle projection.
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.
Neglecting term "opposite".. In third angle projection, what we see are what are we going to draw

First angle and third angle projection are two methods of creating orthographic projections of 3D objects in technical drawing. In first angle projection, the object is positioned between the observer and the projection plane, resulting in the top view appearing below the front view and the right side view appearing to the left. Conversely, in third angle projection, the object is placed behind the projection plane, which positions the top view above the front view and the right side view to the right. These projection methods are standardized in different regions, with first angle commonly used in Europe and third angle prevalent in the United States.
Both third angle and first angle projection display the standard three orthographic views of a part or assembly on a drawing.. The key difference between third angle and first angle is the layout of the part on the sheet.
right side view draw in left side and left side view draw in right side is called third angle projection
any country using in second r fourth angle projection r else what r the advantages between first angle and third angle projetion
they are fools
