A mathematical instrument for laying down and measuring angles on paper, used in drawing or in plotting. It is of various forms, semicircular, rectangular, or circular.

An instrument formerly used in extracting foreign or offensive matter from a wound.

an instrument for measuring degrees of an angle - most commonly a semi - circle which can measure up to 180 ° but full circle 360 ° protractors are available.

a tool or device for determining the measurement of angles; the unit for measurement in elementary school is generally degrees, however, radians may also be used

a half circle subdivided around the edge in degrees and used for measuring angles.

An instrument having a graduated arc for plotting or measuring angles. Protractors are often built-in to machine tools as in the compound slide on a lathe.

A drapery tool by which exact angles are measured (as in bay windows).

drafting instrument used to draw or measure angles

a circular or semicircular tool for measuring angles

a device created in order to divine the degree measure of an angle or to draw an angle with a specific degree measure through the use of a circular measuring scheme

a device for measuring the angle between two intersecting lines

a device that measures angles

an instrument for measuring angles by the displacement method

a tool that lets us draw angles of a specific size, or draw a line in a given direction

a graduated, semi circular instrument for plotting and measuring angles.

Some models of compasses have this feature to allow the user more flexibility in using the compass with a map. Bearings can be more easily plotted with the protractor.

A tool for measuring or drawing angles. When measuring an angle, the vertex of the angle should be at the center of the protractor and one side aligned with the 0° mark. A half-circle protractor can be used to measure or draw angles up to 180°; a full-circle protractor can be used to measure or draw angles to 360°.

A device, usually of clear plastic and circular or D-shaped, used to measure angles.

instrument for setting out and measuring degrees.

A device for measuring angles.

An instrument that measures angles, the Satellite IP Modem protractor provides the current angle of the antenna so that you can adjust it to the antenna angle specified on the Pointing Screen.

An instrument for laying down and measuring angles on paper, used in drawing and plotting.

A tool used to measure exact angles.

An instrument, in the form of a graduated semicircle, which is used to plot and measure angles.

An instrument used to find the degree measure of an angle.

A tool used to measure the size of an angle in degrees (Lesson 0.2).
