Imaginary line (mathematics)
In complex geometry, an imaginary line is a straight line that only contains one real point. It can be proven that this point is the intersection point with the conjugated line. It is a special case of an imaginary curve. An imaginary line is found in the complex projective plane P(C) where points are represented by three homogeneous coordinates formula_1 Boyd Patterson described the lines in this plane: Felix Klein described imaginary geometrical structures: "We will characterize a geometric structure as imaginary if its coordinates are not all real.: According to Hatton: Hatton continues, Imaginary line (mathematics
