"Cyclic Touching Circles Around Triangle"
 
   Dear All My Friends,

In the triangle ABC we select one direction, say A to B to C to A to B...
At vertex A: construct a circle (A1) touching 2 lines of vertex A
At vertex B: construct a circle (B1) touching 2 lines of vertex B and sharing with (A1) one touching point.
At vertex C: construct a circle (C1) touching 2 lines of vertex C and sharing with (B1) one touching point.
Again at vertex A...

Generally, at one vertex, we construct a circle touching 2 lines of the vertex and sharing with previous constructed circle one touching point.

Please prove that the process is stop after construction of six circles and all touching point are concyclic!

Best regards,
Bui Quang Tuan
