4 gon 0.8906
Basic Geometry
The 4 edge lengths are:
- e1 : $ - \frac{\sqrt{6}}{3} + \frac{\sqrt{2}}{2} + 1 $ ≈ 0.891
- e2 : $ - \frac{\sqrt{6}}{3} + \frac{\sqrt{2}}{2} + 1 $ ≈ 0.891
- e3 : $ - \frac{\sqrt{6}}{3} + \frac{\sqrt{2}}{2} + 1 $ ≈ 0.891
- e4 : $ - \frac{\sqrt{6}}{3} + \frac{\sqrt{2}}{2} + 1 $ ≈ 0.891
The 4 angles are:
- α1 : $ \frac{\pi}{2} $ ≈ 90.0000°
- α2 : $ \frac{\pi}{2} $ ≈ 90.0000°
- α3 : $ \frac{\pi}{2} $ ≈ 90.0000°
- α4 : $ \frac{\pi}{2} $ ≈ 90.0000°
