Central symmetry: After rotating180 around a point, the figures completely overlap.
Axisymmetry: when a piece of paper is folded, the folding line is the symmetry line.
Think about it, a figure that can completely overlap by rotating 180 around a point definitely has a center line to make it symmetrical!
1, the central symmetric figure must be an axisymmetric figure!
And your question is vague. I haven't understood what your problem is after thinking for a long time. Tell me more, brother! If you can't understand it in simple words, you can use pictures and texts to explain it.
