Miquel Circles

For a Triangle $\Delta ABC$ and three points $A'$, $B'$, and $C'$, one on each of its sides, the three Miquel circles are the circles passing through each Vertex and its neighboring side points (i.e., $AC'B'$, $BA'C'$, and $CB'A'$). According to Miquel's Theorem, the Miquel circles are Concurrent in a point $M$ known as the Miquel Point. Similarly, there are $n$ Miquel circles for $n$ lines taken $(n-1)$ at a time.
