👉 Separatrices are a type of geometry problem that involves finding the lengths of diagonals, or "separatrix" lines, in a given polygon. A diagonal is a line segment joining two non-adjacent vertices of a polygon. In this context, a separation is when the sum of the lengths of the diagonals of a polygon is equal to twice its perimeter. For example, consider a regular pentagon (a 5-sided polygon). The pentagon has four sides and five angles
