Explanation:

When a line is parallel to one plane and inclined to the other, the projection of the line on the plane to which it is parallel will show its true length. The projected length on the plane to which it is inclined will always be shorter than the true length.

S. No.	Orientation/Position of line	Front view or elevation	Top view or plan
