​

Geomètricus is an independent project for people who enjoy solving geometry problems, understanding the ideas behind them and seeing them explained beautifully.

I’m Guillem, a graphic designer and web developer with a long-standing interest in mathematics, especially geometry.

​

Geomètricus is where I bring these interests together through geometry problems, visual explanations and carefully designed resources.

Your interest and feedback will also help shape what Geomètricus becomes and what I create next.
