This category contains pages concerning Distance between Incenter and Excenter 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 $I$ be the incenters of $\triangle ABC$.
Let $I_a$ be the excenters of $\triangle ABC$ with respect to $a$.
Let $R$ be the circumradius of $\triangle ABC$.
Then:
- $I I_a = 4 R \sin \dfrac A 2$
