~. Use the Poincare disk model at https://www.geogebra.org/m/fUCCfAEj to
make diagrams showing each statement below is false in hyperbolic geometry.
Final versions should include a short explanation as to why the statement is
false, using dynamic calculation if appropriate. For example, the Angle Sum Pos-
tulate sketch should dynamically calculate the angle sum. But I don’t expect the
individual drafts to do this since some of you have a lot more GeoGebra experience.
