Three penetration of two triangular pyramids
The models show the penetration of two triangular pyramids, where three different cases arise. In all these models one pyramid can be pulled out, in order to show quite clear the curve of intersection. In this model all three edges of one pyramide intersect the lateral faces of the other one; the curve of intersection splits up into two distinct polygons.
