Abstract

Disclosed is a multi-functional triangular rule which comprises a triangular rule body. Internal angles of the triangular rule body are respectively 30 DEG, 60 DEG and 90 DEG. The triangular rule is characterized in that the triangular rule body is provided with a hollow cavity which is in an isosceles right triangle shape and protractor scales. The edge of the hollow cavity is provided with scales used for marking the length. The multi-functional triangular rule has the advantages that an external frame of the triangular rule has a usage function of a right angle triangular rule and the internal angles are respectively 30 DEG, 60 DEG and 90 DEG; an internal frame of the triangular rule can be used for an isosceles right triangle rule and a protractor; and the triangular rule has a three-in-one function, is easy to carry along and use and reduces the cost.
