The image shows a non-periodic tiling pattern, and the task is to find the smallest positive angle by which it can be rotated around its center point so that it appears unchanged.

To determine the smallest rotation angle, we need to analyze the rotational symmetry of the pattern. By examining the number of identical sections or repeating units radiating from the center, we can calculate the angle of rotation. 

From the visual structure of the tiling, it appears to have **10-fold rotational symmetry**, meaning that the pattern repeats itself 10 times as you go around the center.

Thus, the smallest angle of rotation is given by:

\[
\frac{360^\circ}{10} = 36^\circ
\]

So, the tiling can be rotated by **36 degrees** around its center point without changing its appearance.
