In projective geometry, desargues theorem states that two triangles are in perspective axially if and only if they are in perspective centrally. The desargues configuration when desargues theorem holds in a projective plane we get ten points and ten lines with each line containing exactly three of the ten points and any three lines intersecting at exactly one of the ten points. Axial perspectivity means that lines ab and ab meet in a point, lines ac and ac meet in a second point, and lines.
