The set {1,2,4,5,10,11,13,14} (blue) has no 3-term arithmetic progression, as the average of every two set members (yellow) falls outside the set. Roth proved that every progression-free set must be sparse.

The optimal square packing in a square can sometimes involve tilted squares; Roth and Bob Vaughan showed that non-constant area must be left uncovered
