Problems solved by technology

[0002] In the process of learning mathematics, protractors, rulers and compasses are usually used, but the existing protractors, rulers and compasses are all single products. The protractor can only measure angles, and the compass can only be used to draw circles. A ruler can only measure length and draw a straight line. Therefore, the existing protractors, rulers and compasses have a single function and a small range of applications.

Description

technical field [0001] The invention relates to a learning appliance, in particular to a multifunctional mathematics learning appliance. Background technique [0002] In the process of learning mathematics, protractors, rulers and compasses are usually used, but the existing protractors, rulers and compasses are all single products. The protractor can only measure angles, and the compass can only be used to draw circles. Straightedge can only measure length and draw straight line, therefore, existing protractor, straightedge and compass have single function, and the range of application is small. Contents of the invention [0003] The problem to be solved by the present invention is to provide a multifunctional mathematics learning tool with simple structure, convenient adjustment and wide application range. [0004] In order to solve the above-mentioned technical problems, the multifunctional mathematics learning appliance of the present invention comprises a protractor,...
