1wat u ve given is centroid...........
d ans must be z1+z2+z3
1well, one not so intelligent method is let z1=(x1,y1) z2=(x2,2) and z3=(x3,y3)
now in the argand plane normally find the orthocentre as u do in coordinate geometry. then the obtained cordinates are the required ones of orthocentre.
1mod(z1-z4)=mod(z2-z4)=mod(z3-z4)
z4= orthocentre..
am i proceedin rit?????????
1@ i mentioned orthocentre then why will i ask centroid
@ mani can u please proceed [2]
11the only method i can think of is conversion to coordinate
@manipal isnt that the definition of circumcentre
it think its wrong :)
11sorry my mistake [2][2][2]
used rong concept[17]
read the question in a haste
spidey join coordinates and draw the perpendicular onto the other side
1arre yaar nahi hote i tried these question isliye request ki thi ki hints mat do ek aur doubt bhi aise hi para hai koi to help karo hamari [2]
62Hint:
a point z such thta
z-z1 is perpendicular to z2-z3
z-z2 is perpendicular to z1-z3
z-z3 is perpendicular to z2-z1
nwo can you try?
what does it mean? (Rotation by 90 degree!)
It is still not an easy question..
