Answer:
False
If the corner of an object is parallel to the viewer, it can still be drawn in one-point perspective. In one-point perspective, all lines that are parallel to each other in real life will converge to a single vanishing point on the horizon line. This means that even if a corner of an object is parallel to the viewer, the lines leading up to that corner will converge towards the vanishing point on the horizon line, and it can still be represented using one-point perspective.
