Coordenades dels vèrtexs
Per un tetraedre truncat d'aresta unitat, les coordenades dels seus vèrtexs són:
- \(V_1=\left(a,-a,b\right)\)
- \(V_2=\left(a,a,-b\right)\)
- \(V_3=\left(-a,a,b\right)\)
- \(V_4=\left(-a,-a,-b\right)\)
- \(V_5=\left(b,-a,a\right)\)
- \(V_6=\left(b,a,-a\right)\)
- \(V_7=\left(-b,a,a\right)\)
- \(V_8=\left(-b,-a,-a\right)\)
- \(V_9=\left(a,-b,a\right)\)
- \(V_{10}=\left(a,b,-a\right)\)
- \(V_{11}=\left(-a,b,a\right)\)
- \(V_{12}=\left(-a,-b,-a\right)\)
on:
- \(a=\frac{\sqrt{2}}{4}\)
- \(b=\frac{3\sqrt{2}}{4}\)
