1. Does anybody have a nice solution to BMO1 2007/8 question 1? I used algebra but got stuck

Algebra is the way to go. It should work out nicely tbh.

I know but i got to a stage where it stopped working because I needed to find out 2007^4 which is huge
4. @physicsmaths how would you solve it?

Let n=2007 then do the algebraic division to get a quadratic.

6. Signing up to this for summer. Wanna get good at problem solving before I go to uni cause atm I'm shocking, didn't even qualify for BMO
7. a fun geo question. Latex is screwed anyway so i'm too lazy to fix it
Given a triangle $ABC$ satisfying $AC+BC=3\cdot AB$. The incircle of triangle $ABC$ has center $I$ and touches the sides $BC$ and $CA$ at the points $D$ and $E$, respectively. Let $K$ and $L$ be the reflections of the points $D$ and $E$ with respect to $I$. Prove that the points $A$, $B$, $K$, $L$ lie on one circle.
8. Could anyone check that its x=0 y=1 and x=3 y=-4 as the solutions to bmo1 1987 question 1. Many thanks
9. ok another one
find the number of solutions to where and p is a prime congruent to 3 mod 4.
10. I feel like I am solving most of the geometry problems using trig is that looked down upon like calculus in olympiads?

Nah it aint looked down upon. Its looked at better then coordinate bashes and stuff.

But i find doing it by pure euclidean is the hardest

Like using constructions and similar triangles and stuff

practice is key.

I know do you have any geometry questions you would be happy to share. Sorry I couldnt understand the previous geometry question you posted without latex
17. Btw guys Irish Mathematical Olympiads is another massive source of questions at the exact level of BMO1/2 so you can do thos if you run out.

lol dw that ones kinda hard
idk bmo has a lot of nice geometry questions. how much do you know about cyclic quadrilaterals etc?

ptolemys theorem and that the opposite angles add to 180

ptolemys theorem and that the opposite angles add to 180
okay
some other useful stuff is angle bisector theorem and angles subtended on the same arc but im sure you know that already
okay try this one
in a quadrilateral ABCD where BC//AD the diagonals intersect in P. the circumcircles of ABP and CPD intersect AD in S and T respectively. Let the midpoint of ST be . Show that MB=MC.
