Question 13
Bob's mosaic uses grey or white shapes described as having 3,4,5 or 6 vertices. In every row and every column, both the number of white shapes and the total vertex count are odd. A wave replaced exactly two original shapes. The damaged mosaic is shown.
These five loose pieces were found nearby.
Which two are the original pieces that were replaced?
Editorial counting convention: count a star's five outer tips as 5 for this puzzle, rather than its ten boundary vertices. The five labelled loose pieces are individual objects, each usable at most once.
