Embodiment Construction

[0013] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes two fitting rulers 1 hinged at the ends, wherein one of the rulers 1 is fixed with an angle arc 2 fitting the two ruler faces, and the surface of the angle arc 2 is provided with an angle scale 3; the angle arc 2 is a right angle arc.

[0014] When drawing in the learning process, use ruler 1 to draw a straight line. When drawing an angle, fix a ruler 1, adjust the position of another ruler 1 through the calibration of the angle arc 2, and draw according to the specified angle Out of the triangle line, the size of the angle can also be measured through the angle arc 2.
