👉 The term "longilateral" is a mathematical concept in geometry that refers to a polygon with four sides (or edges) and four vertices. In other words, it is a polygon with four straight lines connecting its vertices. A regular longilateral shape is one where all of the angles are equal, which means that each side of the polygon is an equal length and has the same measure. For example, consider a square (a type of quadrilateral), which has four sides each measuring 4 units
