Question

Unit circles with centres at r1 and r2 are drawn in two non-parallel planes

with equations r · k1 = p1 and r · k2 = p2 respectively (where the kj are unit vectors and

the pj ≥ 0). Show that there is a sphere passing through both circles if and only if

(r1 − r2) · (k1 × k2) = 0 and (p1 − k1 · r2)^

2 = (p2 − k2 · r1)^
