1. Conclusion
The primary focus of this paper has been on the construction of custom tools in GeoGebra for creating hyperbolic lines and hyperbolic circles in the Poincaré disk model. The hyperbolic line tool is robust and works well in all cases including when points A and B are in the interior of γ, on the boundary of γ and when they are on the same diameter. The hyperbolic circle is similarly robust and works for the full range of positions of the center point A and point B within and on γ. Tools for creating hyperbolic segments and rays can be constructed in a manner similar to that of hyperbolic lines with some modifications. If the reader wishes to create a more complete suite of tools for working with the Poincaré disk, then it is worth noting that the construction of hyperbolic perpendicular bisectors, hyperbolic midpoints, hyperbolic perpendicular lines and hyperbolic angle bisectors mimic their corresponding Euclidean compass and straightedge constructions.
