Archimedes's Regular Heptagon

مسبّع أرشميدس

Drawing a regular heptagon inside a circle cannot be done with ruler and compass alone. Archimedes solved it by a method known only from Thabit ibn Qurra's Arabic translation of his treatise, and Arab geometers, al-Quhi among them, went on to write on it.
