Mirrors What happens when we have two mirrors? What if the mirrors are parallel? What if instead they intersect? What if we make the angle between them larger or smaller? How many images do we see? Try the activity and followup here. Rotations Rotations can give powerful effects, especially when you combine multiple rotations or introduce… Read More Playing with Symmetry
For this project, you have a choice to work in symmetry patterns or in geometric sculpture. Option A: Symmetry Patterns Develop a portfolio of symmetry patterns. Your portfolio should include a total of 5 patterns. The choice of symmetry type is up to you, as is the choice of the type of work and method… Read More Project 3
We started talking about symmetry last week with the snowflakes exercise. Since we won’t be together on Monday, post two (or more) images related to symmetry. These could be pictures that you take of symmetry in the world, your own sketches or other work, or symmetric pieces you like done by others. Post them in… Read More Symmetry comments!
This week we finished with symmetry. You can click here for notes in which I review the types of symmetry (reflection, rotation, translation, and glide reflection) and go over how we categorize rosettes, frieze patterns, and wallpaper patterns. I also gave out this flowchart that can be used to help you classify a wallpaper pattern. Your… Read More Week 8 Recap: Symmetry wrap-up and a first taste of fractals
A tessellation is basically a way to tile a floor (that goes on forever) with shapes (called tiles) so that there is no overlapping and no gaps. We typically look at using a tile of the same shape repeatedly (think of a floor of square tiles or a walkway of rectangular bricks). Sometimes we use two shapes… Read More Week 7 Recap: Tessellations
This week we started by exploring frieze patterns, patterns with repetition (translation) in one direction. A good review of this can be found here. That link has a different system of naming for the frieze patterns than we discussed in class, but look here for the names we used (the hop, jump, etc). Frieze patterns will… Read More Week 6 Recap: Frieze and Wallpaper Patterns
This week we began to look at symmetry, starting by talking about what we mean by symmetry, and trying to group images with similar types of symmetry. For math folks, a symmetry is a rigid motion (no breaking, bending, or shrinking) that leaves a figure looking the same — you can rotate, reflect in a mirror,… Read More Week 5 Recap: Symmetry
