heptagonal
Having seven edges
Heptagonal means having seven sides and seven angles, describing a polygon or something shaped like one: a heptagonal tower, heptagonal tiles.
The seven-sided figure is uncommon in everyday life compared to squares or hexagons, making heptagonal shapes notable when they appear in architecture or design.
