البرهان الثالث (Info)
برهان هندسي، باستخدام تشابه المثلثات:
ِAD منصف الزاوية A، نسقط عمود من B على AD يقطعه في F، ونسقط عمود من C على امتداد AD يقطعه في E.
المثلث AEC يشابه المثلث AFB
( لأن E و F قائمتان و لأن AD منصف A)
المثلث DEC يشابه المثلث DFB
( لأن E و F قائمتان و للتقابل بالرأس)
وهو المطلوب إثباته .
