Main article: Positioning goniometer A miniature electro-mechanical goniometer stage. This type of stage is used primarily in the field of lasers and optics. The second is an Angle, Side, Angle (ASA) construction where two angles and the side between them is known. Example 1: Find the measure of each angle of an equilateral triangle with the help of a protractor.

Milanese, Gordon. "Reliability and concurrent validity of knee angle measurement: Smart phone app versus universal goniometer used by experienced and novice clinicians". Manual Therapy. 5: 1–6. Move the on-screen protractor using (desktop) left mouse drag or (tablet) single finger touch and drag. Protractor is highlighted in green when moving.Since the spaces, both on the main scale and the Vernier scale, are numbered both to the right and the left from zero, any angle can be measured. The readings can be taken either to the right or to the left, according to the direction in which the zero on the main scale is moved. Reflex Angles: Reflex angles measure more than 180 degrees but less than 360 degrees.They are often used in navigation and surveying, as well as in sports and recreation.For example, a football field is marked with reflex angles to indicate the end zones. The basic technique remains in use, although the equipment has changed dramatically. Goniometers are widely used for military and civil purposes, [5] e.g. interception of satellite and naval communications on the French warship Dupuy de Lôme uses multiple goniometers. Modern rehabilitative therapy motion capture systems perform goniometry at the very least measuring active range of motion. [11] While in some cases accuracy may be inferior to a goniometer, measuring angles with a motion capture system is superior at measuring during dynamic, as opposed to static situations. Furthermore, using a traditional goniometer takes valuable time. In the clinical context, performing manual measurements takes valuable time and may not be practical.

A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position. The term goniometry derives from two Greek words, γωνία ( gōnía) ' angle' and μέτρον ( métron) ' measure'. [1] The protractor is a commonly used type in the fields of mechanics, engineering, and geometry. There are many different types of angles and each type has its own unique properties.Here are some of the most common types of angles: So whether you want to measure an angle, measure the degree, or compare two angles, the online protractor is the perfect tool for the job! Measuring angles with the online protractor Use a protractor to measure the angle from the left-hand endpoint of the given side, mark it with a cross and draw a line from the endpoint through this mark.A protractor in math is a very useful tool for measuring angles of different shapes, such as triangles, squares, hexagons, and others.
