How many types of triangular rulers are there I want to know?

There are 6 types of triangular rulers, which are °. A triangular ruler has two triangular plates, which are right-angled triangles formed by °.

and ° to form a right triangle.

Splice two triangles at different anglesThe two acute angles in the right triangle formed by ° in the triangular ruler are both 45°, so the question becomes how many angles can be put together by the combination of ° and °. After splicing in pairs, you can get six angles.

There are two types of triangular rulers. Each triangular ruler consists of two special right-angled triangles. One is an isosceles right-angled triangular ruler, and the other is a right-angled triangular ruler with special angles (hereinafter referred to as a slender triangular ruler).

A triangular ruler has 1 right angle and 2 acute angles. Both acute angles of the isosceles right-angle triangular ruler are 45°. Two identical isosceles right triangles can be put together into a square, or they can be put together into a larger isosceles right triangle.

The two right-angled sides of an isosceles right-angled triangular ruler are equal in length.

Functions of the triangular ruler:

The multi-functional triangular ruler is a circle drawing mechanism that is composed of a rotating ring and a turntable at the two acute angles of the original triangular ruler, a pendulum needle-shaped angle drawing mechanism is installed at the protractor, a frame is installed at the bottom edge, a groove rail is provided in the frame, and a parallel line drawing mechanism composed of a positioning mechanism composed of a schedule plate, an elastic material and a slider embedded in the groove is installed in the groove to facilitate sliding.

It maintains the function of the original triangular ruler, adds the function of drawing parallel lines, small circles and can draw angles, and is compact and easy to use. The acute angles of the slender triangular rulers are 30° and 60°, respectively. Two identical slender triangular rulers can be put together to form a regular triangle.

The length of the hypotenuse of a slender triangle is twice the length of the short right-angled edge.

There are 6 types of triangular rulers, which are °. A triangular ruler has two triangular plates, which are right-angled triangles formed by °.

and ° to form a right triangle. The equilateral right angle is a triangular ruler with a back seat on one side. The main drawing is right angles and 45 degree angles.

The role of the triangular ruler:The more common is used for comics, and there are roughly three kinds of rulers needed to draw comics: ruler, triangular ruler, and cloud-shaped ruler, among which the ruler is the most used, which is generally used to draw grid boxes and draw straight lines; The second is the triangular ruler, which is used to draw parallel lines and right-angled sides; The cloud ruler is used to draw curves.

A triangular ruler is two rulers. The triangular ruler we use is generally two rulers, one is a foot isosceles right triangle, the other is a right triangle with an inner angle of 60 degrees, and the other internal angle is 30 degrees. Because with these two rulers, it is possible to draw almost all geometric figures, except for special ones.

So a triangular ruler is two rulers.

The role of a rulerA ruler, also known as a measuring ruler, is a tool used to draw line segments, especially straight ones, to measure length. There is usually a scale on the ruler to measure the length. Some rulers, with a special shape such as a letter or a circular hole in the middle, are convenient for users to draw, and are usually used to measure the length, which are generally divided into tape measures, vernier calipers, rectangular rulers, and rulers.

The snake ruler is a ruler dedicated to drawing curves. A triangular ruler is a ruler of a right-angled triangle or an isosceles triangle, which is convenient for drawing parallel or vertical lines. Slide rule: A calculation tool. A soft ruler is often used to measure parts of the human body.
