This category contains pages concerning Distance between Excenters of Triangle in Terms of Circumradius:
Let $\triangle ABC$ be a triangle whose sides are $a$, $b$ and $c$ opposite vertices $A$, $B$ and $C$ respectively.
Let $I_b$ and $I_c$ be the excenters of $\triangle ABC$ with respect to $b$ and $c$ respectively.
Let $R$ be the circumradius of $\triangle ABC$.
Then:
- $I_b I_c = 4 R \cos \dfrac A 2$
