    They’re not really mentioned in more advanced math. It’s all polygons.

    Ok, triangles are often treated as a special case. But for anything else it’s a n-sided polygon.

      You mean regular polygons. A rhombus is an irregular polygon. Triangles are also all polygons. An equilateral triangle is a regular one.
