ثلاث نقاط – جزء أ - درجة 2

مهمة

معطاة النقاط الثلاثة: $A(-2,-3)\space\space,\space\space B(5,-3)\space\space,\space\space C(2,1)$

جدوا بطرق مختلفة مساحة المثلث ABC.
جدوا نقطة F بحيث أن: $S_{ABC}=S_{ABF}$
هل اجابتكم لبند 2 كانت إجابة وحيدة؟ فسروا اجابتكم.

درجة

يمكنكم الاستعانة بالتطبيق المرفق.

تطبيق

عيّنوا إحداثيات النقطة F: سجلوا إحداثي x ، وإحداثي y. ومن ثم اضغطوا Enter.
يمكن عندما تظهر النقطة F في هيئة المحاور جرّها وتغيير إحداثياتها، وبذلك تتغيّر مساحة المثلث ABF بالملائمة.
