Workshop: Tessellations on the Poincare' Disk - Exploring Hyperbolic
Geometry with The Geometer's Sketchpad
In this hands-on computer workshop, participants will use The
Geometer's Sketchpad to visit hyperbolic geometry and the Poincare'
disk in a progression leading from exploration of the 5th postulate
to construction and classification of the (infinite number of)
regular tessellations that become possible in this non-Euclidean
geometry. A smattering of historical background and connections to
Escher's famous Circle Limit series may make this an appealing
standalone unit to consider at the upper secondary or undergraduate
level, as well as in preservice or inservice teacher development.
No prior Sketchpad or hyperbolic geometry experience
