Ethnomathematics: Rotation in Jepara Carving
In the application of the concept of rotation, this occurs in the process of drawing a pattern on carving media (wood) so that the nature of rotation occurs in the results of the engraving. In the process of making a pattern image on the carving media, the engraver rotates the pattern that has been made so that the second pattern and so on becomes a pattern with a different position arround some point, but contains the same carved motif which will produce a complete carved motif. For example, we can be seen in the following image.
Pay attention to the rotation elements in the following Jepara carvings!
Pay attention to the environment around you!
Mention something in your environment that uses / contains the concept of rotation!
