Question

The 4th quadrant is in which position?

(a) Below H.P, behind V.P

(b) Above H.P, behind V.P

(c) Above H.P, in-front of V.P

(d) Below H.P, in-front of V.P

I got this question by my school teacher while I was bunking the class.

My question is from Planes of Projections and Four Quadrants in section Loci of Points & Orthographic Projections of Engineering Drawing

Answer 1

Right answer is (d) Below H.P, in-front of V.P

Easiest explanation: The position of reference planes will be similar to quadrants in x, y plane co-ordinate system. As the 4th quadrant lies below the x-axis and in front of the y-axis here also the 4th quadrant is below H.P, in front of V.P.
