    Q1: What is an angle protractor?
    A1: An angle protractor is a measuring tool used to measure angles. It typically consists of a flat, plastic or metal base with a pivoting arm that has a graduated scale marked in degrees. The arm can be rotated to any angle, allowing the user to measure the angle between two lines or the angle of a single line relative to a horizontal or vertical axis.

    Q2: How do I use an angle protractor?
    A2: To use an angle protractor, place the base of the protractor on the surface you wish to measure the angle of. Align the protractor's vertical or horizontal axis with one of the lines you want to measure the angle between. Then, rotate the protractor's arm until it is aligned with the other line you want to measure. Read the angle measurement from the graduated scale on the arm.

    Q3: What are some common applications of angle protractors?
    A3: Angle protractors are commonly used in a variety of applications, including carpentry, metalworking, engineering, and drafting. They are often used to measure the angle of a cut to ensure it is accurate and to create angled cuts for various projects. They are also useful in determining the slope of a roof or the angle of a hillside. In addition, angle protractors can be used in mathematical and scientific applications to measure angles between lines or to calculate trigonometric functions.

    Tips: What are the measurements of a protractor?

    A protractor is a measuring tool used to measure angles. The measurements on a protractor are typically marked in degrees and are divided into 360  degrees. The protractor is usually a semi-circular or circular tool with a base marked with numbers from 0 to 180 degrees in a clockwise direction, and sometimes also marked in a counterclockwise direction. The degrees are further divided into smaller units, such as minutes (') and seconds (").

    The markings on a protractor can vary slightly depending on the specific type and brand, but some common features of a protractor include:

    • A straight edge or base line helps to align the protractor with the angle being measured.
    • A center point, sometimes marked with a small hole, is used as a reference point for measuring angles.
    • Two sets of numbers or markings, one on each side of the center point, indicate the degrees and smaller units of measurement for the angle being measured.
