The origami game is an interesting toy, which can not only kill time, but also learn geometry knowledge. This article will teach you how to fold an equilateral triangle from a square piece of paper.

Find point B.

Find the point B on the center line of the square paper and make sure that the distance from B to A and C is equal to the side length AC of the square. This step is a bit challenging, but as long as AC is obliquely folded from A to C and coincides with the center line, the point on the crease is B!

Fold AB and CB

Fold AB and CB, and you can get a perfect equilateral triangle ABC! An equilateral triangle is a treasure. Its three angles are all 60 degrees, so it is also called equilateral triangle or regular triangle.

Discover the characteristics of equilateral triangles

The three high lines of an equilateral triangle not only bisect the base vertically, but also intersect at one point, so that the equilateral triangle can be divided into six overlapping right triangles, three isosceles triangles and three quadrangles. BC' is also an equilateral triangle, and its area is a quarter of that of ABC.
