If we construct a line parallel to line AB, then the line cannot construct a line of reflection from point A to point B as there must be a distance between the line of reflection of AB and the parallel line.
If we construct a line that passes through A and B, it will also not be a line of reflection as for reflection, there must be a line acting as a mirror
If we construct a line through B which is perpendicular to the line segment AB, then it is the perpendicular distance from the point A to the point
