Q.

The traces of plane are not intersecting at xy reference line then the plane is

A. inclined to h.p and perpendicular to v.p
B. parallel to h.p and perpendicular to v.p
C. perpendicular to both reference planes
D. inclined to v.p and perpendicular to h.p
Answer» B. parallel to h.p and perpendicular to v.p
Explanation: when a plane has two traces, they, produced if necessary, intersect in xy except when both are parallel to xy reference line as in case of some oblique planes. and in those some specific are plane parallel to one reference and perpendicular to other.
