右图绕中心顺时针旋转 后，结果是哪一个？
Which of the following represents the result when the figure shown at the right is rotated clockwise about its center?
答案：B
解答：
顺时针旋转 后，每个图形移动到顺时针方向的下一个位置：上方的三角形移到右下，右下的正方形移到左下，左下的圆移到上方。
因此结果应为圆在上方，正方形在左下，三角形在右下，且每个图形形状保持不变。
所以正确答案是 B。
A clockwise turn of sends each shape to the next position clockwise: the triangle at the top moves to the lower right, the square at the lower right moves to the lower left, and the circle at the lower left moves to the top.
The result therefore has a circle on top, a square at the lower left, and a triangle at the lower right, with each shape keeping its original form.
Thus, the correct answer is B .
