Abstract
The utility model belongs to the technical field of teaching appliances, in particular to a triangle drawing teaching aid for a math class. The triangle drawing teaching aid comprises a first board rule, a second board rule, a protractor and an adjusting board rule, wherein one end of the first board rule and one end of the second board rule are respectively hinged, and a board body of the first board rule and a board body of the second board rule are respectively provided with a first oblong hole and a second oblong hole extending along with the length directions of the first board rule and the second board rule; the protractor is arranged on one side of the first board rule and can slide along with the length direction of the board body of the first board rule; and a board body of the adjusting board rule is provided with a third oblong hole extending along the length direction of the adjusting board rule, a first fastening piece is arranged between the third oblong hole and the first oblong hole, and a second fastening piece is arranged between the third oblong hole and the second oblong hole. When in use, the triangle drawing teaching aid disclosed by the utility model is provided with the movable protractor and the adjusting board rule, so that a required triangle can be conveniently and accurately drawn on one step, and the problems that the work load of the math teacher is increased and the class time is also wasted because a math teacher can not draw the required triangle on one step are solved.
Description
Technical field
The utility model belongs to the teaching aid technical field, relates in particular to a kind of mathematics class with the triangle teaching aid of mapping.
Background technology
When math teacher is made a triangle at blackboard, often do a limit with ruler earlier, and then measure needed angle with inclinometer, and then do other limit with ruler, unusual trouble just when when only knowing the length of three sides of a triangle, making triangle, and can not disposablely make needed triangle, the workload that has increased teacher in the middle of invisible is also wasted time in classroom.
The utility model content
The purpose of this utility model is to provide a kind of mathematics class with the triangle teaching aid of mapping, be intended to solve math teacher and when blackboard is made triangle, can not disposablely make needed triangle, increased the problem that teacher's workload is also wasted time in classroom in the middle of invisible.
The utility model is to realize like this, a kind of mathematics class is with the triangle teaching aid of mapping, described mathematics class comprises with triangle mapping teaching aid: the first hinged board foot of an end and second board foot are arranged respectively, the plate body of described first board foot is provided with first elongated hole that extends along its length direction, and the plate body of described second board foot is provided with second elongated hole that extends along its length direction; The protractor that is arranged on described first board foot, one side and can slides along its length direction; Regulate board foot, the plate body of described adjusting board foot is provided with the 3rd elongated hole that extends along its length direction, is provided with between described the 3rd elongated hole and described first elongated hole between first securing member, described the 3rd elongated hole and described second elongated hole and is provided with second securing member.
As a kind of improvement, be provided with index line with the hinged end end of described first board foot on described second board foot, an end end that is connected with described first board foot on the described adjusting board foot is provided with index line.
Owing to adopt technique scheme, the mathematics class that the utility model provides with the obtained beneficial effect of triangle mapping teaching aid is: can determine leg-of-mutton angle because first board foot is provided with movably protractor, and regulate board foot and first board foot, the junction of second board foot can be regulated, just can regulate the length of side, so length on known Atria limit, the length on both sides and angle thereof, all can make things convenient for during one edge lengths and three angles big or small and disposablely accurately make required triangle, solve math teacher and when blackboard is made triangle, can not disposablely make needed triangle, increased the problem that teacher's workload is also wasted time in classroom in the middle of invisible.
Description of drawings
Fig. 1 is the mathematics class that provides of the utility model with the structural representation of triangle mapping teaching aid;
Wherein: 1, first board foot, 11, first elongated hole, 2, second board foot, 21, second elongated hole, 3, regulate board foot, the 31, the 3rd elongated hole, 4, protractor, 5, first securing member, 6, second securing member, 7a, index line, 7b, index line.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, this mathematics class comprises with triangle mapping teaching aid: the first hinged board foot 1 of an end and second board foot 2 are arranged respectively, the plate body of this first board foot 1 is provided with first elongated hole 11 that extends along its length direction, and this plate body of 2 is provided with second elongated hole 21 that extends along its length direction; The protractor 4 that is arranged on first board foot, 1 one sides and can slides along its plate body length direction; Regulate board foot 3, the plate body of this adjusting board foot 3 is provided with along being provided with between first securing member 5, the 3rd elongated hole 31 and second elongated hole 21 between the 3rd elongated hole 31, the three elongated holes 31 of its length direction extension and first elongated hole 11 and is provided with second securing member 6.
In the present embodiment, when using this mathematics class with triangle mapping teaching aid, because being provided with movably protractor, first board foot can determine leg-of-mutton angle, and regulate board foot and first board foot, the junction of second board foot can be regulated, just can regulate the length of side, so length on known Atria limit, the length on both sides and angle thereof, all can make things convenient for during one edge lengths and three angles big or small and disposablely accurately make required triangle, solve math teacher and when blackboard is made triangle, can not disposablely make needed triangle, increased the problem that teacher's workload is also wasted time in classroom in the middle of invisible.
In the utility model, the hinged end end of this second board foot 2 and first board foot 1 is provided with index line 7b, and the end end that this adjusting board foot 3 is connected with first board foot 1 is provided with index line 7a.
The mathematics class that the utility model provides comprises with triangle mapping teaching aid: the first hinged board foot of an end and second board foot are arranged respectively, the plate body of this first board foot is provided with first elongated hole that extends along its length direction, and the plate body of this second board foot is provided with second elongated hole that extends along its length direction; The protractor that is arranged on first board foot, one side and can slides along its plate body length direction; Regulate board foot, the plate body of this adjusting board foot is provided with the 3rd elongated hole that extends along its length direction, is provided with first securing member between the 3rd elongated hole and first elongated hole, and is provided with second securing member between second elongated hole; During use, because being provided with movably protractor, first board foot can determine leg-of-mutton angle, and the junction of regulating board foot and first board foot, second board foot can be regulated, just can regulate the length of side, so when the length on the length on known Atria limit, both sides and angle, an edge lengths and three angles big or small, all can make things convenient for and disposablely accurately make required triangle, solve math teacher and when blackboard is made triangle, can not disposablely make needed triangle, increased the problem that teacher's workload is also wasted time in classroom in the middle of invisible.
