Tiling a Triangle with Two Polyiamonds
Introduction
Which pairs of polyiamonds can
tile a triangle?
Here I show some minimal tilings of triangles by copies of two polyiamonds.
Every triangular polyiamond has an imbalance of cells pointing up
and cells pointing down.
Thus any two polyiamonds with balanced cell orientations cannot tile a
triangle.
Please write if you solve an unsolved pair.
Carl Schwenke and Johann Schwenke contributed many new or improved
solutions.
