Talk:Triangular tiling

radius of euclidean tiling = 1^2 / 2 * sqrt(1^2 - 2^2 / 4) = 1/0

used isot circumradius formula with b=2 and ℓ=1

circumradius of polytope with the verf's circumradius as $$r$$ is $$\frac{1}{2\sqrt{1-\frac{r^2}{4}}}.$$

if calculating radius of verf has division by zero, just return the verf's radius as infinity.
