Rhombus 42

Fillygon rhombus-42 corners

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{1}{\phi^{2}} \right )} + \pi $ ≈ 138.1897°
  • α2 : $ 2 \arctan{\left (\frac{1}{\phi^{2}} \right )} $ ≈ 41.8103°
  • α3 : $ - 2 \arctan{\left (\frac{1}{\phi^{2}} \right )} + \pi $ ≈ 138.1897°
  • α4 : $ 2 \arctan{\left (\frac{1}{\phi^{2}} \right )} $ ≈ 41.8103°
