Question
Let A, be the center of the square inscribed in acute triangle ABC with two vertices of the square on
side BC (as shown in the figure below). Thus, one of the two remaining vertices of the square lies on
side AB and the other on side AC. Points B, and C, are defined in a similar way for inscribed squares
with two vertices on sides AC and AB, respectively. Prove that lines AA,, BB, CC, are concurrent.
