Three penetrations of two triangular prisms
The models show the penetration of two triangular prisms. One prism can be pulled out, in order to show clear the polygon of penetration in the other prism.""
Three different cases of penetration can be distinguished:
In the left model all three edges of the white prism intersect the faces of the second prism.""
In the centre model one edge of the one prism intersects one edge of the other prism. One gets two polygons of intersection with one corner in common.""
In the right model one edge of the one prism does not intersect the other prism.
