This category contains pages concerning Area of Triangle in Terms of Exradius:
Let $\triangle ABC$ be a triangle whose sides are $a$, $b$ and $c$ opposite vertices $A$, $B$ and $C$ respectively.
Let $\rho_a$ be the exradius of $\triangle ABC$ with respect to the excircle which is tangent to $a$.
Let $s$ be the semiperimeter of $\triangle ABC$.
Then the area $\AA$ of $\triangle ABC$ is given by:
- $\AA = \rho_a \paren {s - a}$
