A set of geometric diagrams including two squares and a rectangle in the top row, and a matching set in the bottom row, all labeled with Greek letters corresponding to geometric ratios.

A secondary set of geometric diagrams featuring squares, rectangles, and line segments, utilized to demonstrate the geometric proofs found in the text.
