Pohlke-Schwarz theorem
From Encyclopedia of Mathematics
(Redirected from Pohlke–Schwarz theorem)
Any complete plane quadrilateral can serve as the parallel projection of a tetrahedron similar to a given one.
The theorem was first stated in a different form by K. Pohlke (1853), and was generalized by H.A. Schwarz (1864).
