ongelijkbenige

Ongelijkbenige is a term in geometry referring to shapes with unequal side lengths. In triangle classification, an ongelijkbenige driehoek (unequal - sided triangle) has three distinct side lengths, meaning no two sides are identical. This type contrasts with equilateral triangles (all sides equal) and isosceles triangles (at least two sides equal). The term originates from Dutch, where "ongelijk" denotes "unequal" and "benige" relates to sides/edges in geometry. Such shapes are fundamental in mathematics, architecture, and engineering, where precise side measurements are vital for structural stability or design accuracy.
