Abstract
The utility model relates to a triangular prism straightedge. The utility model can be used to measure length, draw a straight line and plot by office staff or students, and can also be used as a teaching apparatus for physical experiment. Thereby, geometric and physical characteristics of light can be apprehended. The utility model can be used to press paper, documents, materials, etc.
Description
The utility model relates to a kind of cultural tools.
At present society to go up existing culture and education more single with common ruler purposes, though have can deserve to be called the toy chi, that is nothing but being painted with pattern on chi, pattern can simply change irregularly sometimes, interest is very dull.
