Answer explanation

A protractor is a measuring instrument that has a calibrated angle or degree ranging from 0 to 360 degrees. It is primarily used to plot angles or measurements on a drawing. A triangle is a shape with three sides, a ruler is a straight edge measuring tool, and a rectangle is a four-sided shape with opposite sides that are equal in length. None of these options match the description of an instrument used for measuring and plotting angles like a protractor does.
