2. Conic section - Wikipedia

   en.wikipedia.org/wiki/Conic_section

   A conic is the curve obtained as the intersection of a plane, called the cutting plane, with the surface of a double cone (a cone with two nappes).It is usually assumed that the cone is a right circular cone for the purpose of easy description, but this is not required; any double cone with some circular cross-section will suffice.

3. Circumconic and inconic - Wikipedia

   en.wikipedia.org/wiki/Circumconic_and_inconic

   In Euclidean geometry, a circumconic is a conic section that passes through the three vertices of a triangle, [1] and an inconic is a conic section inscribed in the sides, possibly extended, of a triangle. [2] Suppose A, B, C are distinct non-collinear points, and let ABC denote the triangle whose vertices are A, B, C.

4. Linear system of conics - Wikipedia

   en.wikipedia.org/wiki/Linear_system_of_conics

   In algebraic geometry, the conic sections in the projective plane form a linear system of dimension five, as one sees by counting the constants in the degree two equations. The condition to pass through a given point P imposes a single linear condition, so that conics C through P form a linear system of dimension 4.

5. On Conoids and Spheroids - Wikipedia

   en.wikipedia.org/wiki/On_Conoids_and_Spheroids

   Consisting of 32 propositions, the work explores properties of and theorems related to the solids generated by revolution of conic sections about their axes, including paraboloids, hyperboloids, and spheroids. [1] The principal result of the work is comparing the volume of any segment cut off by a plane with the volume of a cone with equal base ...
