Correct answer: A
When a plane is parallel to the projection plane , it appears in its true size . Important Points (English) When a plane is parallel to the plane of projection , its true size and shape are seen.
There is no foreshortening because all points of the plane are at the same distance from the projection plane.
True size is visible on the projection plane to which the object is parallel .
If the plane is parallel to HP (Horizontal Plane) , true shape appears in the top view .
If the plane is parallel to VP (Vertical Plane) , true shape appears in the front view .
This concept is widely used in engineering drawing to understand object geometry clearly.
