Hello Guys!

Triangle Similarity is one of the most beautiful topics in High School and Olympiad Math. A lot of problems on the same have been posted on Brilliant, starting from the popular ones to the completely unnoticed. I have to decided to compile most of them in this note, just for practice and fun. Please pitch in!

This is what you need to do:

- Write the name of the problem and link it.

Problems must be from level 3 to 5 only.

Please do take part, thanks a lot!
