I'm working on this problem.(adsbygoogle = window.adsbygoogle || []).push({});

The only given information is the circle is inscribed into the triangle. And you have to find the radius of the circle.

The answer is...

[tex]\frac{2\sqrt{5}}{3}[/tex]

Can someone come up with an explaination as to why? It's been a few years since I had geometry, and have tried everything I remembered with bisectors and whatnot.
