http://www.icoachmath.com/math_dictionary/incenter.html WebIn conclusion, the three essential properties of a circumscribed triangle are as follows: The segments from the incenter to each vertex bisects each angle. The distances from the incenter to each side are equal to the inscribed circle's radius. The area of the triangle is equal to \frac {1} {2}\times r\times (\text {the triangle's perimeter}), 21
