Description

Hexagonal teaching aid

Technical Field

The utility model relates to the field of geometric teaching assistance, in particular to a hexagonal teaching aid.

Background

Mathematics is a discipline of combining figures, each of which has the existence of intuitive shapes, such as polygonal teaching. A hexagon is one type of polygon, meaning all polygons with six sides and six corners. The regular hexagon can be drawn by using a compasses ruler alone. Because when the regular hexagon is inscribed in a circle, the radius of the circle is just equal to the side length of the regular hexagon, and the longest diagonal of the regular hexagon is equal to the diameter of the circle. The ancient Chinese theory of circumference and diameter has the term "Zhou san Jing Yi", and can be regarded as the result obtained by adopting the approximate graph of regular hexagon as a circle.

Important knowledge points of, for example, a junior middle school math regular hexagon are:

the inner angles are equal, and the 6 sides are equal;

with the outer angle sum being fixed equal to 360 degrees, an inner angle of 180- (360/6) =120 degrees is pushed out, so an inner angle of 120 degrees;

the regular hexagon is divided into 6 congruent regular triangles with the center being over-center, the height of the regular triangle is calculated as v 3/2×a, and the height of each triangle is calculated as v 3/4×a2 by the pythagorean theorem, so that the area of the regular hexagon is v 3/4×a2×6=3 v 3/2×a2s regular hexagon= (3 v 3/2) a2 (wherein a is the side length).

However, in the hexagonal teaching process, a teacher generally draws a hexagon on a blackboard or displays the hexagon through a hexagonal teaching aid, the drawing is not visual on the blackboard, the general hexagonal teaching aid is planar, students are displayed by hands, and the teaching aid is inconvenient, particularly when the teaching aid needs to be displayed simultaneously and written, and the teaching aid is not interesting.
