Within a triangle are three tangent circles to each other and on two sides of the triangle. The lines that go from each vertex passing through the tangent point of each pair of circumferences, are concurrent and intersect at the first point of Ajima-Malfatti X179. The lines that go from each excenter through the tangent point of each pair of circles, are concurrent and intersect at the second point of Ajima Malfatti X180.
