Rhombus — AMC & AIME Problems
27 problems
Practice every real AMC 8, AMC 10, AMC 12, and AIME problem that uses Rhombus — a geometry concept — each with a professionally curated solution, many with a video solution too, from LIVE by Po-Shen Loh. Browse all concepts or the full past-contest archive.
LIVE focuses on challenge. As a social enterprise, we also explain standard school concepts one at a time, for free, on our sister site Expii. For this idea: Properties of Rhombi.
All problems are used with official legal permission of the Mathematical Association of America (MAA).
