Online compendium of solutions to Connelly's problems in Euclidean geometry
Statuses of all problems: S (s) denotes that the problem is solvable and its solution is given, S (ns) denotes that the problem is proved solvable but its solution is not given, L that the problem is locus dependent, R that the problem is redundant, U that the problem is unsolvable, while UK denotes that the status of the problem is still unknown.
