👉 Semiformed is a term used in mathematics, specifically in geometry and algebra. It refers to a shape that has its sides equal in length but whose angles are not necessarily equal. This means that two of the angles may be equal or unequal. For example, consider the regular pentagon (a five-sided polygon). The angle at each vertex is 108 degrees, which is the smallest possible value for an interior angle in a regular polygon. However, if we had made one of the
