Question

The object we see in our surrounding usually without drawing came under which projection?

(a) Perspective projection

(b) Oblique projection

(c) Isometric projection

(d) Orthographic projection

The question was posed to me in an online quiz.

Asked question is from Basics of Orthographic Projections in section Loci of Points & Orthographic Projections of Engineering Drawing

Answer 1

The correct answer is (a) Perspective projection

To elaborate: Perspective projection gives the view of an object on a plane surface, called the picture plane, as it would appear to the eye when viewed from a fixed position. It may also be defined as the figure formed on the projection plane when visual rays from the eye to the object cut the plane.
