Abstract
A device for generating angles has a ruler-shaped basic rail having a first guide extending in a longitudinal direction of the basic rail. A stop rail is arranged in the first guide of the basic rail and is rotatable and slidable into different positions relative to the basic rail and securable in the different positions. The stop rail has an underside provided with depressions positioned at an acute angle to one another and forming a star-shaped arrangement. The basic rail has a projection that engages the depressions.
