Question

A triangle is placed perpendicular to horizontal plane and inclined to vertical which of the following is true?

(a) Front view-line, top view- triangle

(b) Front view- triangle, top view- line

(c) Front view –line, top view-line

(d) Top view-line, side view- line

I had been asked this question in my homework.

The doubt is from Projection of Planes Inclined to one of the Reference Plane & Perpendicular to other topic in section Projection of Planes of Engineering Drawing

Answer 1

Right answer is (b) Front view- triangle, top view- line

The best explanation: When a plane is perpendicular to one of the reference planes and inclined to the other, its inclination is shown by an angle which its projection on the plane to which it is perpendicular, makes with xy. Its projection on the plane to which it is inclined, is smaller than the plane itself.
