Rhombus 48
Basic Geometry
The 4 edge lengths are:
- e1 : $ 1 $ ≈ 1.000
- e2 : $ 1 $ ≈ 1.000
- e3 : $ 1 $ ≈ 1.000
- e4 : $ 1 $ ≈ 1.000
The 4 angles are:
- α1 : $ - 2 \arctan{\left (\frac{\sqrt{5}}{5} \right )} + \pi $ ≈ 131.8103°
- α2 : $ 2 \arctan{\left (\frac{\sqrt{5}}{5} \right )} $ ≈ 48.1897°
- α3 : $ - 2 \arctan{\left (\frac{\sqrt{5}}{5} \right )} + \pi $ ≈ 131.8103°
- α4 : $ 2 \arctan{\left (\frac{\sqrt{5}}{5} \right )} $ ≈ 48.1897°
