Applications

Angle protractors are commonly used in fields such as construction, engineering, and carpentry to measure angles for cutting and fitting materials. They are also used in mathematics and physics to solve problems involving angles and trigonometry.

Tips: What are the different types of angle protractors?

There are several types of angle protractors used for measuring angles, including:

• Protractor with a Half-Circle: This is the most common type of protractor and has a half-circle shape with markings from 0 to 180 degrees. It is used to
  measure angles from 0 to 180 degrees.
• Full Circle Protractor: This protractor has a full circle with markings from 0 to 360 degrees. It is used to measure angles greater than 180 degrees.
• Digital Protractor: This protractor uses electronic sensors to measure angles and displays them digitally. It is more accurate and easier to read than traditional protractor.
• Vernier Protractor: This protractor has a vernier scale that allows for more precise measurement of angles. It is often used in technical fields like engineering and physics.
• Bevel Protractor: This protractor is used for measuring angles in machine and metalworking applications. It has a swiveling arm that can be adjusted to different angles.
• Universal Bevel Protractor: This protractor is similar to the bevel protractor but can be used to measure angles in three dimensions. It is commonly used in tool and die making and machine design.
• Optical Protractor: This protractor uses a magnifying lens and reticle to measure angles with high precision. It is often used in optical and metrology applications.
