Summary
Description |
English: The picture shows, that complanarity in a affine space with more than 2 points on each line and in a projective space can be fully characterized by collinearity, see german description for details. Deutsch: Ein Punkt D in einem affinen Raum mit mehr als 2 Punkten auf jeder Geraden liegt genau dann in der Ebene, die durch ein Dreieck ABC bestimmt ist, wenn die Verbindungsgerade DE von D mit einem Punkt E auf der Geraden AB, der aber weder gleich A noch gleich B ist, wenigstens eine der Dreiecksseiten BC oder AC in einem Punkt F schneidet. |
