The Figured Wheel is a historical device used for teaching and demonstrating mathematical concepts, particularly in geometry. It consists of a circular disk divided into sections, each representing different values or functions. This tool helps students visualize relationships between numbers and shapes, making complex ideas more accessible. Often associated with the work of mathematicians like Leonhard Euler, the Figured Wheel serves as an educational aid in classrooms. It can illustrate various mathematical principles, such as fractions, ratios, and proportions, enhancing the learning experience for students of all ages.
