What Should I Consider Before Buying?

1. Accuracy: Look for a 360 protractor that guarantees precise measurements, preferably with clearly marked degree increments and reliable construction.
2. Durability: Consider the material and build quality of the protractor to ensure it can withstand regular use without losing accuracy. Sturdy materials like stainless steel or high-quality plastic are excellent choices.
3. Size and Portability: Determine the size that suits your needs; smaller protractors are more portable, while larger ones might offer better readability. Additionally, check if it fits easily into your bag or pencil case.
4. Visibility: Opt for a 360 protractor with clear markings and well-contrasted colors. This will make it easier for you to read measurements accurately, even in low-light conditions.

Different Types of 360 Protractors

• Circular Protractors: This traditional style features a circular shape, commonly made of transparent plastic or metal. They usually come in diameters ranging from 4 to 6 inches, allowing you to measure angles up to 360 degrees.
• Digital Protractors: These modern protractors have an electronic display that provides accurate angle readings. They often come with additional features like built-in levels, memory functions, and the ability to measure angles in both degrees and radians.
• Angle Rulers: While not strictly protractors, angle rulers serve a similar purpose by allowing you to measure angles accurately. They usually have an adjustable arm and can measure angles up to 360 degrees. Some models even feature angle-locking mechanisms for added convenience.

How to Use a 360 Protractor

Using a 360 protractor is relatively straightforward, but let's go through the basic steps:

1. Place the center of the protractor over the vertex of the angle you want to measure, ensuring the base line aligns with one side of the angle.
2. Check the measurements along the curved edge of the protractor to find the appropriate degree mark that corresponds to the other side of the angle.
3. Read the angle value where the other side of the angle intersects the protractor's curved edge.
4. Take note of the measurement and use it for your intended purpose.

Remember, practice makes perfect! It may take a few tries before you become fluent in accurately measuring angles.
