AI Drawing Prompt Reference

Draw an illustration of a gear mechanism showing the geometric relationship of gear rotation and meshing. Start with a line segment, then draw a circle centered at one of its points. Mark multiple points along the segment and rotate them around the center repeatedly to form the teeth of the gears. Label the angles of rotation to demonstrate how the gears mesh and rotate together, suitable for high school students learning geometric transformations and mechanical principles.
