If the line at infinity is a secant line of a conic then the conic is a hyperbola?

Show this quad is cyclic

Proof of why conics map to conics after a perspective transformation

Is there a geometric construction that finds the intersection of two conics, given only five points on each?

Given four points, determine a condition on a fifth point such that the conic containing all of them is an ellipse

Why homogenise these vectors?
