The third set of aerobics, how to change the formation of seven people? At least six variations are required. We are a university physical education class, not a major, and we have to study for the final exam. How to change everything Start the triangle, the first combination, the second eight beats can be rectangular, the third eight beats can be changed into two oblique rows, and the fourth eight beats can be transposed. The first combination is in the opposite direction. The first eight beats become two horizontal rows, the second eight beats can become a circle, the third eight beats move on the circle, and the fourth eight beats return to the triangle. There are six formations now, haha, you have to improvise.
