Ellipse : locus of points which moves such that sum of the distances from two fixed point is constant. Hyperbola : locus of points which moves such that differences of the distances from two fixed point is constant. Ellipse : two focci, two axis ,major and minor, closed and bounded region ,four vertices and centre Hyperbola : two focci, two axis ,transverse and conjugate , un bounded region ,two vertices and centre. Ellipse : eccentricty less than one. Hyperbola : eccentricity more than one. Solution Ellipse : locus of points which moves such that sum of the distances from two fixed point is constant.
