Brain Teaser

Ok say there is a rough spiral shape in a 3 dimensional plane. You have the coordinates of several points of the spiral shape. We will call these points spiral-A points.

51.1 18.3 -43.2
25.2 24.2 -46.6
10.7 16.6 -42.2
6.6 6.0 -36.1
7.0 -2.9 -30.9
13.7 -11.0 -26.3
20.9 -11.4 -26.0
31.9 -7.6 -35.2
22.6 -8.4 -35.6
16.4 -3.0 -32.6
16.8 6.5 -27.1
26.6 -0.1 -31.1 *4
27.8 2.4 -34.0
28.0 -0.1 -34.9 *3
31.8 -0.1 -33.8 *2
33.0 -1.4 -31.7
30.3 0.0 -31.8 *1

Then say that spiral-A is rotated, and you are given 3 points of it's new location.

99.2 -11.2 9.5
98.2 -11.0 13.7
97.9 -9.5 3.6

Determine the other corresponding points of the spiral, and explain how you found them.
