In [[recreational mathematics]], a '''polyabolo''' (also known as a '''polytan''' or '''polytrong''') is a shape formed by gluing [[Special right triangles#45–45–90 triangle|isosceles right triangles]] edge-to-edge, making a [[polyform]] with the isosceles right triangle as the base form. Polyaboloes were introduced by [[Martin Gardner]] in his June 1967 "[[Mathematical Games column]]" in ''[[Scientific American]]''.<ref>{{cite journal |last=Gardner |first=Martin |authorlink=Martin Gardner |date=June 1967 |title=The polyhex and the polyabolo, polygonal jigsaw puzzle pieces |journal=Scientific American |volume=216 |issue=6 |pages=124–132|doi=10.1038/scientificamerican0367-124 }}</ref>
