Interesting solution to a type problem I've had; points cannot be directly added to points. But, say finding the center of a triangle, it's (t[0]+t[1]+t[2])/3. The solution is that affine combination of points is allowed.

A line can also be thought of as an affine map

 F(t) = (1-t)t0 + (t)t1

Menelaos' Theorem:

 given l1, l2
 p1 = Line( l1(t0), l2(t0 )(t1)
 p2 = Line( l1(t1), l2(t1 )(t0)

and this works if there are more lines and more parametric points. The order of the points does not matter.

6.4 Covers degree reduction; given n points, produce the closes possible curve with n-1 points.
