muting's tetrahedron


this is the one that our group made in July 13, our group members are jenny, Susan, and muting. we use a lot of group work. the tetrahedron is a regular, equilangular, and equilateral triangle. it is a poly hadron. there are many triangle and different triangle shape in this tetrahedron. it include centroid, othocenter, incenter and circumcenter. we can find it by using patty paper or paper, but this one is different, because we use straw and yarns to make it. it is fun^.^
