Figure 9.
The image shows four rectangular pieces of material, laid out horizontally on a green surface. Each piece varies in length and features markings including letters, lines, and shapes. The top and bottom pieces have a 'M' marking, while the middle two pieces include different markings, such as small blue dots and a zigzag pattern. The arrangement appears systematic, with the pieces aligned to form a cohesive horizontal display. The texture of the material suggests a paper-like consistency, and the overall appearance hints at a possible educational or technical purpose.Samples with notched shape
