も同じである。 As shown in the drawing, the triangle ruler is 90 degrees, 45 degrees,
At 45 degrees, I attached a protractor to the oblique side, and at 90, 60, and 30 degrees, I added scales on the oblique sides that were higher toward the outside from the center, symmetrically, and the scale in Figure 2 was replaced with Figure 3. Even after devising a new triangular ruler, this triangular ruler has two additional functions compared to the conventional triangular rulers. 45 degrees,
The same goes for triangular rulers that are not 45 degrees, 30 degrees, or 60 degrees.
