### Note

Plural: hexagons; adjective: hexagonal. Hexagon means 6 (hex = six, gon = angle): sides × 6 for counting, or side length × 6 for the perimeter of a regular one. Trap: do not confuse with a pentagon (5), a heptagon (7) or an octagon (8). Only a regular hexagon has all sides equal; an irregular one still has 6 sides.
