Abstract
The invention relates to a foldable triangular ruler which belongs to the field of stationery. The foldable triangular ruler mainly aims to solve the problem that an ordinary triangular ruler is difficult to be placed in a pencil box and is liable to be broken after being placed in other places. The foldable triangular ruler structurally comprises an isosceles triangular ruler main body, wherein corresponding straight flanges of two right-angle triangular rulers are hinged with each other through a folder, so as to the isosceles triangular ruler main body; angle gauge scales are marked in the middle of the isosceles triangular ruler main body; and a through hole is formed on outer edge of an angle gauge. The foldable triangular ruler can be used as the angle gauge. As the folder is arranged in the middle of the isosceles triangular ruler main body, the foldable triangular ruler can be folded to be used as a right-angle triangular ruler. The multi-purpose foldable triangular ruler is convenient to use and carry, and saves storage space.
