What is RHO value for ellipse, Parabola and hyperbola?

As the picture shows, if Rho is 0.5, then the conic is a parabola. If Rho is greater than 0.5, then the conic is a hyperbola. If Rho is less than 0.5, then the conic is an ellipse

RHO value of parabola is 0.5, RHO value of Ellipse is between 0&0.5,RHO value of hyperbola is between 0.5&1

Ellipse had RHO value less than 0.5, Parabola is 0.5 and Hyperbola above 0.5.

Parabola has RHO values of 0.5, Ellipse has RHO value between 0 & 0.5 and Hyperbola has RHO value b/w 0.5 & 1.0.
