A triangle ABC.
Line AD divide equally the angle BAC, i.e., BAD = CAD
Line AE divide equally heline BC, i.e., BE=CE
From E, make a line EF perpendicular to line AD. cross point F, i.e. From F, make a line FG paralell to Line AB, cross line AE with G
Connect point B G and extend to cross AC with H
 
Proof AH = HC
