Rhombus 71

Fillygon rhombus-71 normal

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{2}}{2} \right )} + \pi $ ≈ 109.4712°
  • α2 : $ 2 \arctan{\left (\frac{\sqrt{2}}{2} \right )} $ ≈ 70.5288°
  • α3 : $ - 2 \arctan{\left (\frac{\sqrt{2}}{2} \right )} + \pi $ ≈ 109.4712°
  • α4 : $ 2 \arctan{\left (\frac{\sqrt{2}}{2} \right )} $ ≈ 70.5288°
