Can you solve the last question from last year's Hamilton Maths Olympiad (aimed at students aged 15). It's a very nice geometry problem that's a real test for even the strongest students in this age group.

Any students taking the paper next year (on Thursday 19th March 2026) or in the future can try more questions like these with hints and full solutions in a totally free course here: https://t.co/BDEqkgybmO
