[PDF][PDF] On Pohlke's type projections in the hyperbolic case

R Manfrin - Int. J. Geom, 2024 - academia.edu
Abstract Let OP1, OP2, OP3 be three non-parallel segments in a plane ω. We find the
necessary and sufficient conditions for the existence of the common inscribed ellipse EI and …

[PDF][PDF] A note on a secondary Pohlke's projection

R Manfrin - Int. J. Geom, 2022 - ijgeometry.com
Given three segments OP1, OP2, OP3 in a plane ω, which are not contained in a line, we
find a simple condition for the existence of two distinct ellipses centered at O and …

[PDF][PDF] On the Circumscribing Ellipse of Three Concentric Ellipses

GE Lefkaditis, TL Toulias, S Markatis - Forum Geom, 2017 - academia.edu
Consider three coplanar non-degenerate line segments OA, OB, and OC, where only two of
them can be collinear. Three concentric ellipses are then formed, say c′ 1, c′ 2, and c′ 3 …
