Question: Ahavas Sholem Synagogue has windows that contain the shape that is in what form?
Sentence (from "Star of David"): Its shape is that of a hexagram, the compound of two equilateral triangles. Unlike the menorah, the Lion of Judah, the shofar and the lulav, the Star of David was never a uniquely Jewish symbol, although it had been used in that way as a printer's colophon since the sixteenth century.
