Geometry next to mathematics
Mathematics covers numbers, equations and the subject at large, and Formula the written expressions. Geometry is about shape and space: polygons, angles, solids, compasses, constructions and proofs drawn on paper.
The concave polygon
A thin, uncluttered line with nothing else on it, exactly what a worksheet needs. Use it for exercises on area, on convex versus concave shapes, or on splitting a figure into triangles.
The circuit brain
It is here for the word polygon in its source label, not for any geometry. It works better for an article about AI, a tech meetup poster or a slide on neural networks.
