The article discusses some apparently new theorems in projective geometry that are similar in spirit to Pascal's Theorem and Briancon's Theorem. It is informed that Pappus's Theorem goes back about 1700 years. In 1639, Blaise Pascal discovered a generalization in which there was six points that lie on a conic section.

    In this article we present a simple and elegant algebraic proof of Pascal's hexagon theorem which requires only knowledge of basics on conic sections without theory of projective transformations. Also, we provide an efficient algorithm for finding an equation of the conic containing five given...

    A definition of the term "Brianchon's theorem" is presented. This mathematical theorem proposes that if a hexagon is circumscribed about a conic, its three diagonals are concurrent. The theorem, named after Charles-Julien Brianchon, can also be deduced from Pascal's mystic hexaghram theorem.

    The article discusses the property of the hyperbola, which is based on a paper by Euler that revealed the shared properties of general curves and those of conic sections. In trying to find the triangles inside a hyperbola, the diameter is the line M M1 as it is the one that passes through the...

    It is shown that if a plane of PG(3,q), q even, meets an ovoid in a conic, then the ovoid must be an elliptic quadric. This is proved by using the generalized quadrangles T2(5) (5 a conic), W(q) and the isomorphism between them to show that every secant plane section of the ovoid must be a...

    In this paper, a particular shape preserving parametric polynomial approximation of conic sections is studied. The approach is based upon the parametric approximation of implicitly defined planar curves. Polynomial approximants derived are given in a closed form and provide the highest possible...
