Problems solved by technology

[0002] Now the triangle generally has a right-angle triangle and an equilateral triangle. The right-angle triangle can only measure 30°, 60°, 45° and 90°, and the equilateral triangle can only measure 60°. angle, other angles cannot be measured, so the angles that can be measured are too few

Embodiment 1

[0010] Embodiment 1, with reference to figure 1 , a kind of measuring angle triangular ruler, one side of the triangle ruler 1 is provided with a measuring angle scale 3 with the midpoint of this side as a reference point, and the range of the measuring angle scale 3 is 0~180°, and the described angle measuring scale 3 in the triangle ruler 1 In addition, both sides are engraved with a scale 2 for measuring a straight line, and the range of the scale 2 for measuring a straight line is between 0 mm and 100 mm.

Embodiment 2

[0011] Embodiment 2, in the measuring angle triangle ruler described in embodiment 1: the triangle ruler 1 is made of plastic or stainless steel.

[0012] Embodiment, in the measuring angle square ruler described in embodiment 1 or 2: the described square ruler 1 is an equilateral triangle ruler. It can also be a right-angled square, if it is a right-angled square, it can only be that the angle scale is set on the hypotenuse.

Abstract

The invention discloses an angle measuring triangular rule. One side of the triangular rule is provided with angle measuring graduations taking the middle point of the same side as a reference point; the angle measuring graduations are in a range of 0-180 degrees; the other sides of the triangular rule are carved with graduations for measuring straight lines; the graduations for measuring the straight lines are in a range of 0-100 mm; and the triangular rule is made of a plastic or stainless steel material, and is an equilateral triangular rule. Any angle in the range of 0-180 degrees can be measured through the angle measuring graduations on one of the three sides, and straight-line distances of 0-100 millimeters can be measured simultaneously by using the graduations for measuring the straight lines on the other two sides, so that the measuring functions of the triangular rule are verified.

Description

technical field [0001] The invention relates to a learning tool, in particular to a measuring triangle. Background technique [0002] Now the triangle generally has a right-angle triangle and an equilateral triangle. The right-angle triangle can only measure 30°, 60°, 45° and 90°, and the equilateral triangle can only measure 60°. The angle of , cannot measure other angles, so the angles that can be measured are too few. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a protractor triangle capable of measuring multiple angles in view of the deficiencies of the prior art. [0004] The technical problem to be solved by the present invention is achieved through the following technical solutions. The present invention is a measuring angle triangle, which is characterized in that: one side of the triangle is provided with a measuring angle scale with the midpoint of this side as the reference point, and the range of...
