Triakis tetrahedron

Fillygon triakis-tetrahedron normal

Basic Geometry

The 3 edge lengths are:
  • e1 : $ \frac{5}{3} $ ≈ 1.667
  • e2 : $ 1 $ ≈ 1.000
  • e3 : $ 1 $ ≈ 1.000
The 3 angles are:
  • α1 : $ \arccos{\left (\frac{5}{6} \right )} $ ≈ 33.5573°
  • α2 : $ \arccos{\left (\frac{5}{6} \right )} $ ≈ 33.5573°
  • α3 : $ - 2 \arccos{\left (\frac{5}{6} \right )} + \pi $ ≈ 112.8854°
