测试你俩的互动能力

我前一阵子在公司受训，课间做了不少游戏。有一个游戏是测试两人的互动能力，翻版回家让儿子与女儿一玩。

我拿了一张A4的白纸，在上面画了一张图，让儿子看图，在五分钟之内，他必须写一段文字。女儿不能看图，只能看儿子的描述，在五分钟之内，她必须将图画出来。根据女儿的图与原图的相似性，就可以决定两人之间的互动能力。

这是儿子的描述：

Read all steps before drawing:

1.       Hold the paper in portrait position.

2.       Draw a horizontal line across the middle of the paper.

3.       Above the horizontal line and on the left half, draw a circle. The circle should be in the center of the imaginary quarter of the paper, and there should be a space of a radius of the circle on each side.

4.       Above the horizontal line and on the right half, draw an equilateral triangle. The triangle should be in the center of the imaginary quarter of the paper, and about the same size as the circle.

5.       Below the horizontal line on the left half, draw a square. The square should be in the center of the imaginary quarter of the paper. Draw one horizontal line 1/5 of the height of the square from the top across the square. Draw another horizontal line 4/5 of the height of the square down across the square.

6.       Below the horizontal line on the right half, draw an S. The S should be in the center of the imaginary quarter of the paper. The bottom part of the S should continue spiraling inwards for half a rotation.

女儿画得基本正确，就是左上方的圆圈低了些。

根据这些文字描述，你能在A4纸上画吗？你的图与下面的图示是否相似？
