Suppose excircle triangle $$ABC$$ opposite point $$A$$ offending side $$BC$$ at point $$A_1$$. Defined point $$B_1$$ on $$CA$$ and $$C_1$$ point on $$AB$$ analog, respectively using excircles opposite $$B$$ and $$C$$. Suppose that the center point of the circle outside the triangle $$A_1B_1C_1$$ are in the outer circle of the triangle $$ABC$$. triangle $$ABC$$ is a/an $$\text{__________}$$.

Note:

Excircle triangle ABC opposite the vertex A is the circle of the offensive line segment BC, AB, after the offending beam B, offensive rays after C. Excircle AC at odds with defi ned B and C are similar.
