図中番号、１は本体、２は角度をしめす線、３
，４は直線を引くための面。BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the straight edge protractor of the present invention. In addition, line 2 measuring the angle from sides 3 and 4 on the drawing
are shown at 10 degree intervals on both sides from the center line (90 degrees to sides 3 and 4), and the intervals between the contact points of side 3 and line 2 are shown at 5 mm intervals. Figure 2 is a diagram of a conventional protractor changed to a rectangular shape.It is the same rectangle, but the angle using the lengths of sides 3 and 4 is similar to the section in the detailed explanation of the invention where ``side surface 3 can be used as a straightedge.'' This invention's method of showing line 2 that measures ``
It is a cross-sectional perspective view of a comparative diagram of a conventional protractor showing angles from a center point to help people understand the "straight-fixed form." Numbers in the figure: 1 is the main body, 2 is the line showing the angle, 3
, 4 is a surface for drawing straight lines.
