Aanmerking. De koorde van een hoek, grooter dan 180°. is gelijk aan de koorde van het supplement van dien hoek.
B.v. Koorde 200°=koorde (360°−200°)=koorde 160°=1,96962.
De koordentafalel kan gebruikt worden om, zonder graadboog, nauwkeurig met behulp van passer en meetliniaal, hoeken uit te zetten. Men beschrijft daartoe met een straal van 1 dM. een cirkelboog en zet daarop uit de koorde van den gevraagden hoek uit. Door de uiteinden van de koorde met het middenpunt te vereenigen, verkrijgt men den hoek.
