Note paper

Abstract

This product is a writing paper with a grid of squares formed by drawing straight lines at equal intervals (e.g., 5 millimeters) both vertically and horizontally. On each horizontal solid line, predetermined color codes (e.g., black circles) and specific color codes different from the predetermined color codes (e.g., white circles) are alternately marked at equal intervals (e.g., at a distance of √3 if the distance between the upper and lower horizontal solid lines is 1). Furthermore, for each predetermined color code on a horizontal solid line, specific color codes are marked at a position of ±90 degrees on the horizontal solid line one position above or below it. As shown in "Reference Figure 3" and "Reference Figure 4" illustrating the usage state, by connecting each predetermined color code or each specific color code, angle lines of angles commonly used in classes, etc. (e.g., 30 degrees, 60 degrees, 90 degrees, 120 degrees, 150 degrees, etc.) can be drawn. In particular, when drawing isometric projections or chemical formulas containing aromatic compounds, these can be easily drawn by appropriately connecting each predetermined color code or specific color code.
