106 Geometry Problems May 2026

If stuck for 20 min, switch to coordinates/complex numbers (but only if allowed in contest – IMO accepts pure synthetic or analytic).

Do you see: cyclic quad? right triangle? homothety between incircle/excircle? radical axis? spiral similarity? 106 geometry problems

What would prove it? Congruence? Concyclicity? Equal angles? Equal products (Power of a point)? Collinearity (Menelaus)? If stuck for 20 min, switch to coordinates/complex

Redraw cleanly. Mark given equalities, angles, midpoints, tangents. If stuck for 20 min
