[0003]
The existing electronic triangle does not support automatic adsorption of vertices and line segments. If users want to align the triangle with the vertices of the line segment, they can only align the vertices or edges of the electronic triangle with the vertices or edges of the line segment through manual fine-tuning. The user experience in the measurement process is poor.

Embodiment 1
[0070] Please refer to figure 1 , an operation method based on the electronic triangle, the operation of the electronic triangle can be applied to platforms such as Android mobile terminal devices, including:
[0071] S1, in the process of moving the electronic settable to a line segment to be measured, judge whether the distance between the apex of the electronic settable and the starting point of the line segment to be measured is less than a preset distance value, if so, automatically set the apex of the electronic settable Move to the starting position of the line segment to be tested;
[0072] Optionally, in the process of moving the electronic triangle, calculate the distance from the coordinates of the vertex coordinates of the electronic triangle to the coordinates of the line segment based on the coordinate set of the starting point and end point of the line segment. When the distance between the two vertices is less than 10px, the vertex will be automatically absorbe...
Embodiment 2
[0102] Please refer to figure 2 , an operation terminal 1 based on an electronic triangular board, comprising a memory 2, a processor 3 and a computer program stored on the memory 2 and operable on the processor 3, the processor 3 implements the embodiment when executing the computer program Each step in one.
Embodiment 3
[0104] Such as Figure 6 As shown, the above-mentioned operation method based on the electronic triangle is applied to the actual scene, that is, the teacher-student interaction in the smart classroom. Specifically, it includes:
[0105] Step 1: The teacher uses the teaching tool menu to trigger the command to open the toolbox, and the command notifies the students to open the toolbox through the network;
[0106] Step 2: The student terminal receives the command to open the toolbox, and displays the toolbox view on the interface;
[0107] Step 3: Students open the triangular plate (isosceles right angle or right-angled triangular plate) through the common tool menu, display the corresponding triangular plate model on the interface, and create a custom canvas in the lower layer of the model;
[0108] Step 4: Students operate the triangular plate, and can move up, down, left, right, zoom, rotate, draw geometric figures on the triangular plate model, move to the vertex of the l...

Abstract
The invention discloses an operation method based on an electronic set square and a terminal. The method comprises the steps: judging whether the distance between the vertex of the electronic set square and the starting point of a to-be-detected line segment is smaller than a preset distance value or not in a process of moving the electronic set square to the to-be-detected line segment; if so, automatically moving the vertex of the electronic set square to the starting point position of the to-be-detected line segment; in the process that the electronic set square is controlled to rotate with the starting point of the to-be-detected line segment as the center so as to approach the to-be-detected line segment, determining whether the included angle between the edge, closest to the to-be-detected line segment, in the electronic set square and the to-be-detected line segment is smaller than a preset included angle or not; and if so, automatically moving one edge, closest to the to-be-detected line segment, in the electronic set square so as to coincide with the to-be-detected line segment. The automatic adsorption of the electronic set square and the to-be-detected line segment is realized, the measurement efficiency and accuracy of the electronic set square are improved, and the measurement experience of a user is increased.
Description
technical field [0001] The invention relates to the field of image drawing, in particular to a method and terminal for drawing an electronic triangle. Background technique [0002] The triangular board is the most common teaching tool in teaching. By operating the triangular board to translate, rotate and other operations, the length can be measured and different geometric figures can be drawn. The practice of operating geometric figures can help users improve their observation, imagination, movement changes, and generalization. ability. The scope of use of the physical triangle is limited, and physical tools and drawing boards must be available to complete. With the advancement of science and technology, electronic square boards have also emerged as the times require. [0003] The existing electronic triangular board does not support automatic adsorption of vertices and line segments. If the user wants to align the triangular board with the vertices of the line segment, h...
