How to spell out hollow arrows with puzzles

Qiaoban is a good toy to exercise creativity and observation.

Here is a brief introduction to the spelling of several common shapes.

Tangram consists of two large isosceles triangular pieces, a medium isosceles triangular piece, two small isosceles triangular pieces, a trapezoidal piece and a square piece.

operational approach

0 1

square

Put the two largest triangles together at right angles to form a large isosceles triangle.

The trapezoidal piece and the two smallest triangular pieces form a straight line and are next to the longest side of the isosceles triangle.

The remaining medium-sized triangles are spelled in the lower left corner.

02

rectangle

The two largest triangular blocks are placed in the lower right corner and the lower left corner, and the point on the longest side is the contact point.

The right angle point of a medium-sized triangular piece is placed in the middle downward.

The two right-angled sides are respectively next to the longest side of the largest triangular block.

The remaining small triangles, squares, small triangles and trapezoidal pieces are placed on the top in turn from left to right, as shown in the figure.

03

triangle

The two largest triangle blocks are spliced into a big triangle, and the right angle side is placed on the left.

Medium-sized trapezoidal pieces and triangular pieces are placed in the middle from top to bottom.

On the far right is a small triangle and a square as shown in the figure.

04

trapeziform

The right angles of the two largest triangular blocks are adjacent to each other to form a trapezoid, which is placed on the far right.

The top is a medium-sized triangle.

Next, from left to right, place the trapezoid, small triangle and square pieces as shown in the figure.

05

parallelogram

As shown in the figure, place a small triangular piece and a trapezoidal piece on the square piece.

On the right are the remaining small triangles and medium-sized triangles.

Finally, put two large triangular blocks on the left and right sides of the square that was put together before.

06

arrowhead

Place the largest triangle in the lower left corner.

Next to its longest side, a trapezoidal piece and a small triangular piece are placed in turn from top to bottom.

A medium-sized triangular block is placed at the top, and a square block is placed at the bottom of the other small triangular blocks.

Finally, put the remaining largest triangle on the far right.

07

Double arrow

Make a square, a small triangle, a medium-sized triangle and a trapezoid as shown in the figure.

Then put the largest triangle on the left and right sides, and the longest side is next to the side of the square.
