manera análoga se obtendrán las otras dos bisectrices.[br]El punto de corte de las bisectrices se denomina incentro que es el centro de la circunferencia inscrita[br]al triángulo.

Para obtener la circunferencia inscrita al triángulo, una vez que tenemos el incentro, bastará con determinar el punto de tangencia con alguno de los lados.[br][br]Para ello, hay que aplicar que la recta tangente en un punto de la circunferencia es perpendicular al radio en dicho punto.
