I gotta draw the figure too. :/
Oh alr
ye reflect karne se direction nahi hoga kya
i mean ye reflection of point about line laga ke ho jayega
wait now im not sure q is correct
I havent done that in 3d rn
@SirLancelotDuLac
can you write the equation of line
now you that the reflected point and this point should satisfy 2 things
Wait wait im telling what i did
ok
Eqn of line hogyi x/l=y/m=z/n
Now let this be equal to lambda
ye
To line ka.mid point comes out lambda l , lambda m and so on
mhm
And also the mid point is alpha + alpha'/2
ye
To mene compare krdia inko
Fir sab plus kardia
Jo equation humko.prove karni thi uska lhs aagya merepe
Rhs mein 2lambda bach gaya
Lambda nahi nikl raha aage
yes but see that is only 1 thing you have used
so you can actually get any point
like say p_1 and P_2, would also satisfy your equation
your reflected point has something else unique about it
Mai smjha nahi
Ek bar shuru se bata do iske aage kya karna
ok acha dekh tu abhi tak sahi gaya
midpoin line me hoga
lakin ye sirb reflected point nahi 100 point satisfy karenge
to wo figure me dekh
reflected point ki kuch khaas baat hai
line ke respect me
Achaa
Baat to sahi ha
dekh paa rha kya khaas baat hai?
Equal dist
actually wo baaki sab point bhi rahenge, kyuki unka midpoint uss line me hai
jaise ko bhi point utha line me fir usko uss point ke about reflect karde
bata du kya?
Bata de
perpendicular hai dekh!
jo inka direction hai wo line se perpendicular hia
Ye to dhyan hi ni dia
Perpendicular aagyi chlo fir
Iske aage to batadeta bhai
