Abstract

The utility model provides a right-angled triangle. Inner triangle pattern cavities with different angles are arranged in the right-angled triangle with scales. With the design, functions of two traditional triangles can be integrated into a whole, a drawing line which can be drawn by two triangles in the past can be drawn by only one triangle now, the angle of 15 DEG and 120 DEG (or 135 DEG) can also be conveniently drawn along the bevel edge of the inner triangle pattern cavities, the function of the triangle can also be extended, such as scales for measuring angles, and the like can be set on the triangle, and the triangle is convenient to use and can save the cost.

Description

Right angle triangle

Technical field

The utility model relates to a kind of right angle triangle.

Background technology

Traditional set square is generally two, and wherein 30 ° of right angle triangle is drawn the oblique line of 30 ° and 60 °, 45 ° of oblique lines of another 45 ° of right angle triangles pictures.In real work, as drawing 30 ° of (or 60 °) oblique lines, draw 45 ° of oblique lines again, this is just must use two set squares constantly to vary just can finish, both inconvenient, efficient is also low.

Summary of the invention

Technical problem to be solved in the utility model provides the right angle triangle that a kind of existing 30 ° of right angle triangle functions also have 45 ° of right angle triangle functions.

For solving the problems of the technologies described above, the utility model by the following technical solutions: a kind of right angle triangle has in the right angle triangle of scale label and is provided with the different interior triangle cavity of angle.

Described right angle triangle such as its three angles are respectively 30 °, 60 °, 90 °, the triangle of interior triangle cavity is respectively 45 °, 45 °, 90 °, two right-angle sides of interior triangle cavity are parallel respectively with two right-angle sides of outer right angled triangle, and the extended line of interior triangle cavity hypotenuse is through the summit at 60 ° of angles of outer right angled triangle, and preferably right angle triangle is marked with along the straight line of triangle cavity hypotenuse, and the two ends of straight line are respectively the summit at 60 ° of angles and 30 ° right-angle side.

Described right angle triangle such as its three angles are respectively 45 °, 45 °, 90 °, the triangle of interior triangle cavity is respectively 30 °, 60 °, 90 °, two right-angle sides of interior triangle cavity are parallel respectively with two right-angle sides of outer right angled triangle, and the extended line of interior triangle cavity hypotenuse is through the summit of a 45 of outer right angled triangle, and best described right angle triangle is marked with along the straight line of triangle cavity hypotenuse, and the two ends of straight line are respectively summit and another right-angle side of 45 ° of a 45.

The utility model adopts above-mentioned design, the function that can integrate two two traditional set squares, as long as arbitrary set square can draw over the figure line that must just can draw with two set squares, also can make things convenient for along the setting-out of interior triangle cavity hypotenuse and directly to mark 15 °, 120 ° (or 135 °), and expanded function thereon also, as being with angle measuring calibration etc. thereon, convenient also cost-saved.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Description of drawings

Fig. 1 is the structural representation of first kind of embodiment of the utility model right angle triangle.

Fig. 2 is the structural representation of second kind of embodiment of the utility model right angle triangle.

The specific embodiment

As shown in Figure 1, first kind of embodiment of the utility model the utility model right angle triangle, three angles of 30 ° of right angle triangles are respectively 30 °, 60 °, 90 °, have scale label and triangle on it and be respectively 45 °, 45 °, 90 ° interior triangle cavity. two right-angle sides of interior triangle cavity are parallel respectively with two right-angle sides of outer right angled triangle, the extended line of interior triangle cavity hypotenuse is through the summit at 60 ° of angles of outer right angled triangle, and be decorated with straight line along triangle cavity hypotenuse, the two ends of straight line are respectively the summit at 60 ° of angles and 30 ° right-angle side. and straight line is divided into 45 ° and 15 ° with 60 ° of angles of 30 ° of right angle triangles, straight line forms 135 ° of (45 °) angles with 30 ° of right-angle sides of 30 ° of right angle triangles, utilizes this straight line to make things convenient for and directly draws or measure 15 ° and 135 ° of angles.

As described in Figure 2, second kind of embodiment of the utility model right angle triangle, three angles of 45 ° of right angle triangles are respectively 45 °, 45 °, 90 °, have the interior triangle cavity that scale label and triangle are respectively 30 °, 60 °, 90 ° on it.Two right-angle sides of interior triangle cavity are parallel respectively with two right-angle sides of outer right angled triangle, and the extended line of interior triangle cavity hypotenuse is through the summit of a 45 of outer right angled triangle, be decorated with straight line along triangle cavity hypotenuse, the two ends of straight line are respectively summit and another right-angle side of 45 ° of a 45.Straight line is divided into 30 ° and 15 ° with one 45 ° of 45 ° of right angle triangles, and another 120 ° of (60 °) angles of right-angle side formation of straight line and 45 ° of right angle triangles utilize this straight line to make things convenient for and directly draw or measure 15 ° and hexagonal angle.

Also have angle measuring calibration on the right angle triangle, more than the central point of angle measuring calibration of two embodiment at the hypotenuse mid point of interior triangle cavity.Also can be on the utility model expanded function, as band curve cavity etc., convenient also cost-saved.
