What is the figure of plane oblique section cone? It's an ellipse if you cut a cylinder obliquely. I know, Ask 2, 3 floor plane oblique section conic get figure is ellipse? Yes or no?

Although I don't know what you mean, the elliptic hyperbolic parabola belongs to the conic curve. If you put two cone tips together, it is similar to the placement of two funnel tips. When you cut a cone vertically, it forms a parabola. When you cut a cone obliquely, it forms an ellipse. But you should pay attention not to be parallel to the bevel of the cone. If it is parallel, it becomes a parabola. Is it useful for you
