Catalogue of Convex Polydrafters
A polydrafter is a polyform
made by joining equal drafters,
30°-60°-90° right triangles,
at their short legs, long legs, hypotenuses, or half hypotenuses.
Polydrafters whose cells belong to a common polyiamond (triangle) grid
are sometimes called proper polydrafters.
Polydrafters whose cells depart from the grid are called extended
For more information see Wikipedia.
Below I show all convex proper polydrafters with from 1 to 6 cells.
The decompositions of the polydrafters into drafter cells are not
The counts and drawings do not include extended polydrafters.
If you find an error or omission, please write.
In this enumeration, mirror images are treated as the same polydrafter.
Puzzle: arrange the four convex proper didrafters to make a convex shape.
Puzzle: arrange the seven convex proper tetradrafters to make a convex shape.
