Description

Premium Transparent 180-Degree Protractor with Ruler

The Premium Transparent 180-Degree Protractor with Ruler in the image is a semicircular instrument used for measuring angles. This type of protractor is designed for precision and ease of use, making it ideal for students, engineers, and designers. The tool integrates multiple features to improve accuracy, including clearly marked graduations, a ruler at the base, and convenient finger holes. This design makes it both practical and ergonomic for everyday use in various mathematical and technical applications.

Key Features

Clear Markings

This protractor features bold, clear numbers and precise graduations that make angle measurements easy to read. The degree markings range from 0° to 180° along the curved edge, with intervals of 1° for detailed measurement. These fine subdivisions ensure the user can measure angles with a high degree of precision, which is particularly beneficial in technical drawing or geometry work. The numbering is displayed in both directions, allowing for measurements to be taken clockwise or counterclockwise without confusion.

Durable Design

The markings on this protractor are either etched or printed with durable, fade-resistant ink, ensuring that they remain visible even after extensive use. The transparent plastic body also allows the user to see through the protractor, ensuring that underlying elements of a drawing or workpiece can still be viewed without obstruction. This helps to ensure accurate placement of the protractor when measuring or drawing angles.

Multi-functional Use

A ruler is integrated along the bottom edge of the protractor, allowing it to serve dual purposes as both a protractor and a straight edge. This makes it useful for tasks that require drawing straight lines in addition to measuring angles. The ruler is graduated in both centimeters and millimeters, enhancing its versatility.

Finger Holes for Easy Handling

The protractor also includes two circular holes near the center. These serve as finger grips, allowing users to hold the protractor securely while positioning it on paper or other surfaces. This design feature enhances the tool’s ergonomics and ease of use, particularly for long-duration tasks where precision placement is required.

Usage Scenarios

This protractor is widely used in classrooms for geometry lessons, in engineering for technical drawing, and in design for precise measurements of angles. The transparent body, coupled with bold markings, helps users make accurate measurements without straining their eyes. Whether it’s measuring angles in diagrams or creating accurate drawings, this tool provides the necessary features for smooth operation.
