0.Construct
three tori of the same size each enclosing the other two.
1.Construct
the surface given by the equation
(x2 + y2
+ z2)2 = 2z(x2+ y2).
2.Construct
this model:
3.Construct
the sphere with this pattern:
4.Construct
six spheres of the same size each touching four others.
5.Construct
the torus by pasting two patches .
6.Construct
one half of a torus so its cross-section consists of two intersecting circles.
(These circles are called Villarceaux circles. Reference: Z.A. Melzak,
Invitation to Geometry, pp.63-68. )
7.Construct
one half of a torus so its cross-section consists of two interlocking circles
in space.
8.Construct the line segments joining
points of the curve with the corresponding center of curvature for the
deltoid.
9.Construct
an animated gif file showing the double generation of the deltoid.
