For a polygon<span> to be '</span>regular<span>' it must have all sides the </span>same<span> length and all interior angles the </span>same. The figure on the right is actually an example of an equilateralpolygon<span> since it has all sides the </span>same<span> length, but it is not a </span>regular polygon<span>because its interior angles are not all the </span>same<span>.</span>
