Summary[edit]
| Description |
Italiano: l'immagine illustra una Rigata conoidica a sostegno proprio avente come direttrici: una parabola ed un'ellisse non complanari. Invece nel caso in cui le direttrici sono formate da coniche non corrispondenti, cioè che non si possono ottenere come sezioni di un stesso cono, si ha come sostegno, di quell tipo di rigata, una curva sghemba. Per cui una possibile classfica delle rigate può far riferimento al tipo della direttrice di sostegno, piana, sghemba, che ha una rigata. |
