Abstract

Provided is a ruler with angle lines. A 60-degree angle line, a 45-degree angle line and a 30-degree angle line are marked on a ruler body, and the 60-degree angle line, the 45-degree angle line and the 30-degree angle line intersect a long edge of the ruler body at one point. The 60-degree angle line, the 45-degree angle line and the 30-degree angle line respectively intersect the other long edge of the ruler body, the included angle of the 60-degree angle line and the long edge of the ruler body is 60 degrees, the included angle of the 45-degree angle line and the long edge of the ruler body is 45 degrees, the included angle of the 30-degree angle line and the long edge of the ruler body is 30 degrees, and the 60-degree angle line, the 45-degree angle line and the 30-degree angle line are dotted lines.

Description

Ruler with angle line
Technical field
The utility model belongs to the stationery field, is specifically related to a kind of angle line ruler that has.
Background technology
Ruler is stationery commonly used in our daily life, especially students, in geometric construction, can often apply to ruler, existing ruler not only plays the effect of measurement, and can draw straight line or line segment with it, but what usually use when drawing the angle is set square or protractor, and students must be carried these instruments in examination or when doing at ordinary times how much topics simultaneously, and missing one will bring inconvenience to drawing the angle.
Summary of the invention
The purpose of this utility model provides a kind of ruler with angle line, and purpose is to have reduced the ruler quantity of using when drawing the angle, uses a ruler can draw common angle.
The technical scheme that the utility model adopts is, a kind of angle line ruler, comprise blade, mint-mark has 60 ° of angle lines, 45° angle degree line and 30 ° of angle lines on the blade, a long limit of 60 ° of angle lines, 45° angle degree line and 30 ° of angle lines and blade meets at a bit, 60 ° of angle lines, 45° angle degree line and 30 ° of angle lines intersect with another long limit of blade respectively, and 60 ° of angle lines, 45° angle degree line and 30 ° of angle lines are 60 °, 45 ° and 30 ° of angles with this limit respectively.
Wherein, 60 ° of angle lines, 45° angle degree line and 30 ° of angle lines are dotted line.
The beneficial effects of the utility model are, several angles that the student often runs in doing the topic process can be drawn by 60 °, 45 ° and 30 ° of three angle lines, saved the trouble of carrying multiple picture angle instrument, and can make general ruler uses, article three, angle line adopts dotted line to be imprinted on above the ruler, can detect the degree of accuracy of drawn angle.
Description of drawings
Fig. 1 is a kind of structural representation with ruler of angle line of the utility model.
Among the figure, 1.60 ° of angle lines, 2.45 ° of angle lines, 3.30 ° of angle lines, 4. blades.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.The utility model provides a kind of ruler with angle line, as shown in Figure 1, mint-mark has 60 ° of angle lines 1 on the blade 4,45° angle degree line 2 and 30 ° of angle lines 3, described 60 ° of angle lines 1,45° angle degree line 2 and 30 ° of angle lines 3 meet at a bit with a long limit of blade 4,60 ° of angle lines 1,45° angle degree line 2 and 30 ° of angle lines 3 intersect with another long limit of blade 4 respectively, 5 ° of angle lines 2 of 60 ° of angle line Isosorbide-5-Nitraes and 30 ° of angle lines 3 are 60 ° with this limit respectively, 45 ° and 30 ° of angles, 5 ° of angle lines 2 of 60 ° of angle line Isosorbide-5-Nitraes and 30 ° of angle lines 3 are dotted line.
Using method of the present utility model is, take 60 ° of angles as example, on paper, draw straight line with ruler, a long limit that has three intersection points on drawn straight line and the ruler is coincided, and make the intersection point of 60 ° of angle lines 1 on this limit overlap and mark this point with an end points of drawn straight line, mark the intersection point on 60 ° of angle lines 1 and another long limit of ruler, connect into a line segment with 2, this line segment and drawn straight line are 60 ° or 120 ° of angles, as be hexagonal angle then the drawn straight line of reverse extending namely obtain 60 ° of angles.In like manner can draw other angles.
Use with ruler of angle line not only is to draw 60 ° of angles, 45° angle and 30 ° of angles, combined angle can use this ruler to draw such as 15 ° of angles, 75 ° of angles, 105 ° of angles, 90 ° of angles, hexagonal angle and 150 ° of angles etc. with it, comprised that students does in the topic angle of often using, therefore convenient to use, saved the trouble of carrying multiple picture angle instrument, draw angularpitch for students and save time, improve learning efficiency.
