âVerticesâ are the points on the two arms which are closest; whereas the line segment which connects the arms is called the âmajor axis.â. In a parabola, the two arms of the curve, also called branches, become parallel to each other. In a hyperbola, the two arms or curves do not become parallel. A hyperbolaâs center is the midpoint of the major axis. Hyperbola is given by the equation XY=1. When the difference of distances between a set of points present in a plane to two fixed foci or points is a positive constant, it is called a hyperbola.
