An SPIRAL is a curve…
flat
open
formed by arcs expanding from a central nucleus. It can be...
linear (centers are always over a straight line)
polygonal (the nucleus can be over the vertices of a polygon)
the step is the cumulative distance that the center moves at the end of a turn.
These are different THREE and FOUR CENTER SPIRALS drawn by the 3ESO students. To get these results, there is one spiral starting in each of the 3 or four centers, and the sepace petween each pair of spirals has been filled with colour.
Here you can see some works of our 3rd ESO students of 2022/23.
