Figure below represents a section (shaded) obtained due to intersection by a plane that is parallel to the axes of the cones, what it the section called?(a) Parabola(b) Hyperbola(c) Ellipse(d) CycloidThis question was addressed to me during an online interview.Enquiry is from Curves Used in Engineering Practice topic in division Lettering Practice, Scales & Curves of Civil Engineering Drawing

Answer»

The correct choice is (b) Hyperbola

The best explanation: Hyperbola concept originated in Greek, can be defined as a set of points in a plane whose DISTANCES to two FIXED points in the plane have a constant difference. It is FORMED by the INTERSECTION of a plane with a right CIRCULAR cone. Equation of parabola: x^2/a^2 – y^2/b^2 = ±1.
