A Goniometer comprises of two appendages, generally made of plastic or wood, that are joined by a joint and are normally appended to a round bit of the same material that is marked with various precise estimations. As one appendage is moved towards or far from the other appendage, it is dragged along the round piece and presentations an estimation. Goniometers are produced using various diverse materials and range drastically in size, contingent upon the way of the application.
