Question

A triangular pyramid is placed such that its axis is perpendicular to V.P and one of its base’s edges is parallel to H.P the front view and top view will be _____________

(a) Triangle of base, triangle due to slanting side

(b) Triangle due to slanting side, triangle of base

(c) Triangle of base, rhombus

(d) Rhombus, triangle of base

This question was addressed to me by my college director while I was bunking the class.

This question is from Projections of Solids with Axis Inclined to Vertical Plane and Parallel to Horizontal Plane topic in chapter Projection of Solids of Engineering Drawing

Answer 1

Right answer is (a) Triangle of base, triangle due to slanting side

Easiest explanation: Given a triangular pyramid which means the projection to its base gives triangle shape and other orthographic views give triangle. Here given is pyramid whose axis is perpendicular to V.P so its front view will be triangle of its base and top view will be another different triangle.
