ABDrag an emitter or use its rotate buttons.
Parallel lines in one plane never meet. Perpendicular lines meet at a right angle. Other intersecting lines meet at a different angle.
Two horizontal lines at different heights are parallel. A horizontal line and a vertical line are perpendicular.
Judge the directions of the full lines, even when the visible beam segments do not reach each other.
