Equilateral
In geometry, an equilateral polygon has all sides of the same length. By definition a square is always equilateral (see also rectangle):
x x x x x x x x x x x x x x x x
This triangle is also equilateral:
x x x x x x x x x x x x x x x
Any n-sided polygon which has n sides of equal length can be considered an equilateral. Not all equilaterals are convex geometric shapes: consider that for a pentagon two adjacent sides can be reflected in the line segment joining the two extreme vertices.
