Can anyone explain the logic behind these equations.
Sir ne bataya tha par bhul gya 🥲

+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.what the heck
that's a thing?
I would normally just points the intersection points and find circumcentre and radius to get equation
but this makes it so much easier
how I understand it as is
let's take the general equation of family of lines l1+λl2=0
this equation represents different lines that pass through some fixed point but having different slopes and y-intercepts
similarly if we take three line equations and add another parameter but since a circle is a 2nd degree equation, let's take the lines 2 at a time so l1l2+λl2l3+μl3l1=0
I don't think this answer will suffice
I'll wait and see if anyone else answers
as for the quadrilateral one, there's only one parameter because two lines are just parallel to each other
so slopes are not going to differ
I should prob shush I'm making it more confusing
it was somewhere along the lines of this only ig

i just remember studying this part from here, so i don't exactly know if this will help u resolve ur doubt
hmm this does have that topic but doesnt explain the logic behind it
a friend shared this tht
here, L1L2 represents eqn of a perpendicular bisector and for circumcircle, all perpendicular bisectors should meet at circumcentre, so applying concurrency condn for all three bisectors, u get tht determinant
search mathsmerizing and circle ke pehle ya dusre lecure mai hai
Merko nahi mila can u share link
yoo.?
lol we good?
nah not really

sorry for late reply
@hardcoreisdead maine message wapis nahi dekha tha
sadly ismei bhi logic nahi hai
guess ill ratta it
