Answer:
12: 1; 13: 3; 14: 2; 15: 1; 16: 1; 17: 6; 18: 0; 19: 4
Explanation:
12. 1 line, down the center of the middle bar.
13. 3 lines, each through the center of a short edge and the center of the opposite long edge.
14. 2 lines, one along each axis of the ellipse.
15. 1 line, along the stem. (The picture is distorted enough it is hard to tell if there is any symmetry.)
16. 1 line, perpendicular to the base at the center.
17. 6 lines, 3 along the stems, and 3 between the flowers--all through the center.
18. 0. The figure has no symmetry.
19. 4 lines, all through the center. 1 vertical, 1 horizontal, 2 at 45 degree angles to the vertical.
