製作七巧板 How to Make Tangrams

製作七巧板是一件十分簡單的事。材料亦只是普通文具：一枝筆、一把尺、一把剪刀和一塊紙板／紙張，如喜歡，可準備少許色筆。
Tangrams can be made in a few simple steps.  Materials: pen, ruler, scissor,colored markers or pencils and a firm piece of stationary paper.
1.首先，在紙上畫一個正方形，把它分為十六個小方格。
On the square piece of paper draw a 4 x 4 grid.
2.再從左上角到右下角畫一條線。
Draw a diagonal line from one corner to the other.
3.在上面的中間連一條線到右面的中間。
Draw a diagonal line starting from the top middle center of the page to the side.  (this line will run parallel to the first diagonal)  4.再在左下角到右上角畫一條線，碰到第二條線就可以停了。
Draw a diagonal line in the second box from the top.  The line will extend from the bottom left to the right corner.
5.再在左下角到右上角畫一條線，碰到第二條線就可以停了。
Draw a diagonal line from the bottom left corner of the page to the diagonal line drawn in step 3.
6.從剛才的那條線的尾端開始一條線，畫到最下面四份之三的位置，從左邊開始數，碰到線就可停。
Draw a vertical line from the point of contact in step 5 to the diagonal line drawn through the center of the page.                            7.最後，把它們涂上不同的顏色並跟著黑線條剪開，你就有一副全新的七巧板了。
