To determine which option, when folded along the lines, matches the paper on the left, we need to analyze the fold patterns and positions of each shape. The paper on the left displays a specific arrangement of shapes that, when folded, must resemble one of the provided options. Let's evaluate the options:
This option matches the fold and alignment of the shapes seen on the original paper. The shapes align perfectly when folded as shown, ensuring that the final folded structure resembles the intended design.
Considering the overall alignment and connection of shapes, Option 1 correctly follows the folding line pattern demonstrated in the provided image, resulting in a structure identical to the paper depicted on the left. Therefore, Option 1 is the correct choice.
