| Q. |
A triangle is placed perpendicular to horizontal plane and inclined to vertical which of the following is true. H.T is horizontal trace and V.T is vertical trace? |
| A. | h.t- inclined to xy, v.t- inclined to xy |
| B. | h.t- inclined to xy, v.t- perpendicular to xy |
| C. | h.t-inclined to xy, v.t- parallel to xy |
| D. | h.t-parallel to xy, v.t- perpendicular to xy |
| Answer» B. h.t- inclined to xy, v.t- perpendicular to xy | |
| 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. | |
