Description
- A goniometer has a body that is designed like a protractor. The body can form a full or half-circle and has a scale for measuring angles. The scale can range from 0180 degrees or 1800 degrees for half-circle models, or 0360 degrees for full-circle models.
- The goniometer's arms are hinged together and positioned at specific points on the body. The center of the goniometer is aligned at the joint of interest.
- Some goniometers have easy-to-read inch and centimeter measurements, and clearly marked degree increments.
