Re: IMO Marathon
Sorry for being late. Today was chemistry 2nd part exam.So I was busy.(তারপরও *** খাইসি) Finally, I've found my own solution of problem 4: Let $BT,CT$ intersect $\omega$ at $F,G$. Since the homothety from $T$ sends $F,G$ to $B,C$; So, $FG||BC$ and so $\frac{TF}{TB}=\frac{TG}{TC}$ Note that $MT$ is t...

Re: IMO Marathon
For problem 1; Note that condition 2 implies those two circles are orthogonal. And 1st condition can be found for any $l$ for such two circles. So problem is certainly not true.
