ABSTRACT:
A new geometric instrument-compass for a practical use that allows the trisection of an arbitrary angle as well as retains its effective functionality for operations that can be performed by the conventional compass is disclosed. The design proposed makes this new compass universal in terms of its applicability, namely, it can be used in a vertical position as the conventional compass (depending on the purpose or convenience of the user) and can be used in horizontal position (if it is required to perform the trisection of an angle or even some other operations generally performed by the conventional compass). The simplicity of the design and effectiveness of operations makes this instrument an attractive tool for practical application.
