Klein Disk

The Klein Disk is a non-conformal model of the hyperbolic plane. Later it was discovered that Beltrami independently had discovered this model. A couple experiments for which you can use this: -see how distance works on the disk by moving P & Q -investigate a Klein circle by tracing Q and trying to keep the distance constant. -turn on the 3rd point and try to make an equilateral triangle -turn on the perpendicular through R to AB to investigate right angles in this model
