does this come with a diagram ?

anonymous · Answer

thats the exact question that i need answered too in that picture.

anonymous · Answer

Im sending someone who I know can probably help you

anonymous · Answer

the vertices are all those pointy thingys....
Verices:  A, X, L, F

the definition of a vertice is where 3 or more edges intersect.

anonymous · Answer

What are the edges

anonymous · Answer

the edges are where the faces meet... they are the lines from one vertice to another...:
AX, FX, LX, AF, FL, LA  (there are six edges..)

anonymous · Answer

the faces are the flat part of the tetrahedron... they can be named by the three vertices..
XAF, XFL, XLA, LAF
