Reading time: 1minIf we draw a segment and then draw a perpendicular segment to the first one, it will create an orthogonal line perpendicular to the former segment. If we move the original segment, the line automatically moves, making it orthogonal.
Similarly, a parallel line will be created if we draw a segment and then draw a parallel segment to the first one. If we move the original segment, the line automatically moves, keeping parallel.
