It’s all shaping up

Want to have it your way?

Life’s full of compromises, but you don’t have to be restricted to triangles, squares, and

circles. Regular polygons give you the flexibility to demand exactly the shape you need.

But don’t think that means learning a list of new formulas: you can treat 6-, 16-, and

60-sided shapes the same. So, whether it’s for your own creative project, some required

homework that’s due tomorrow, or the demands of an important client, you’ll have the

tools to deliver exactly what you want.

Would you like to try

some? It’s made with my secret

ingredient: triangles. They’re

just so versatile—I put them in

everything I bake.
