Maths probleme vector help fast [on hold]












-7














I need your help



be ABC a triangle non flat,we define the isobarycentre of the triangle ABC the point G such that :



vector(AG)+vector(BG)+vector(CG)=0



the point G is the centre of gravity of the triangle ABC



QUESTIONS :



1.the respective points I,J and k are placed in the segments (AB),(BC) and (AC).express the vector AJ according to the vector(AB) and the vector(AC).
2 .using the expression: vector(AG)+vector(BG)+vector(CG)=0, express the vector(AG) accrording to the vector(AB) and the vector(AC).
3.show that we can write vector(AG)=Kvector(AJ) "AG=KAJ) " , for a certain k to be determined .
4.deduce the the points A,G and J are aligned .
5.in the same way it can be shown it can be shown that the ponints B,G and k are aligned , as are the points C,G and I , show that G is the the point of intersection of the lines (AJ),(BK) and (CI)
6.what is the position of the point G (the centre of gravity of the triangle ABC)
indication : if AB is a segment , the middle I of (AB) is the poin of intersection between the segment (AB) and its median.

    Welcome to stackexchange. That said I'm voting to close this question because you show no work of your own. If you edit the question to tell us what you tried and where you are stuck we may be able to help. For the future, asking for "help fast" is likely to produce exactly the opposite response.

    Saying you need help fast probably won't help you get help fast - users here like to help people understand the maths they are learning rather than just help them get a homework assignment done on time. If you include where you are stuck on this question, people will be more willing to help as it shows you have put some effort in.
