The image shows a piece of paper with a hand-drawn illustration and annotations. The illustration appears to be a simple mathematical or geometric diagram, consisting of a square with two intersecting lines within it. One line is a diagonal that bisects the square from one corner to the opposite corner. The second line starts from another corner and intersects the first diagonal at a point labeled "A". The area below the intersecting lines and within the square seems to be shaded, indicating it might pertain to the question posed in the text. The annotations are as follows: At the top left, it is labeled "Example 2". To the right of the diagram, there is a number "2.", followed by two questions: A. "What is the largest space enclosed by the dashed, that is, relative to the original square?" B. "How can this space be understood as a logical relation, with the original square, in terms of angular variation?" The handwriting appears to be in cursive with a black pen or pencil. The paper seems aged and has some spots, suggesting it may be an older document or exposed to elements that caused the spots.

The image appears to be a hand-drawn diagram with explanatory text. It shows a rectangular shape labeled "Example 2" and a series of lines and angles within it. The text explains that this shape can be understood as a logical relation with the original square, in terms of an angular transformation.

The image presents a hand-drawn diagram on a piece of paper, accompanied by handwritten notes. The diagram is a square with a smaller square inside it, featuring a diagonal line that intersects the smaller square at its center. The smaller square has a circle at its center, and the diagonal line is labeled "A" at the top-right corner of the square. The handwritten notes are written in pencil and appear to be a discussion of the diagram. The text reads: "What is the logical space indicated by the black dot relative to the original square." and "How can this space be understood as a logical relation, with the original square, in terms of angular variation." The background of the image is a plain white piece of paper, providing a clean and simple backdrop for the diagram and notes. Overall, the image appears to be a visual representation of a mathematical concept or idea, with the diagram and notes working together to convey a specific message or principle.
