What shape describes a protractor?

Rectangular
Semicircle
Square
Triangle

The correct answer is: Semicircle

A protractor is specifically designed to measure angles, and its shape is distinctive to this function. The semicircular design allows for easy measurement of angles from 0 degrees to 180 degrees, providing a clear and intuitive way to read the angle between two lines or segments. This shape also ensures that it can fit snugly against the vertex of the angle being measured, aiding in accuracy. The other shapes listed do not serve the purpose of a protractor. For example, a rectangular shape lacks the curve necessary for measuring angles; a square shape would also not provide the right contour for angle measurement, and a triangular shape is not suitable as a measuring tool for angles. Therefore, the semicircle is the only shape that facilitates the necessary functionality of a protractor, making the choice clear and appropriate.
