  1. AG and HC meet at P, and HC and AB meet at Q. AQ=AH*CD/HD.
    Then AP/PG=AQ/CG=(AH*CD/HD)/CG=(AH*CD)/(HD*CG).
    AG and BO meet at P', and BO and CD meet at T. GT=(OG=HD)*(BE=CG)/(EO=AH)
    Then AP'/P'G=(BA=CD)/GT=CD/(HD*CG/AH)=(AH*CD)/(HD*CG)
    It has been shown that BO and HC meet at the same point of AG.
