@gpjelliss :   Construction of the Nine-Point Circle

 

                                                 A circle is a happy thing to be–
                                                 Think how the joyful perpendicular
                                                 Erected at the kiss of tangency
                                                 Must meet my central point, my avator.
                                                 And lovely as I am, yet only 3
                                                 Points are needed to determine me.
                                                 Christopher Morley (1890-1957)
