1. An instrument for measuring angles, especially in surveying, navigation, or crystallography.
Usage: technical; commonly used in geology, engineering, and medicine
2. A medical device used to measure the range of motion of a joint in physical therapy and orthopedics.
Usage: medical

Examples

• The surveyor used a goniometer to measure the precise angles of the property boundaries.
• A goniometer is essential in crystallography for determining the angles between crystal faces.
• The physical therapist used a goniometer to assess the patient's shoulder mobility after surgery.
• Geologists rely on goniometers to analyze mineral specimens in the laboratory.
• The engineer calibrated the goniometer before taking measurements on the construction site.
• A digital goniometer provides quick and accurate readings of joint angles in clinical settings.
