Having looked into our explanations of transformations and symmetry, over the last weeks, let’s turn to the recent questions that triggered this series. Here we have an adult studying the topic from a good book, but tripping over some issues in the book. We’ll be touching on some topics we haven’t yet looked at, such …
Having looked at geometrical transformations, we can now apply them to the idea of symmetry. We’ll focus on symmetry of figures in a plane.
Last time we looked at what it means to translate, rotate, and reflect figures on a plane. Here, we’ll look at some questions about what happens when these three transformations (and a fourth, the glide reflection) are combined.
Some recent questions have dealt with translation, rotation, and reflection of geometric shapes, so it may be time to look into what we have said about that in the past. Here we’ll look at the meaning of these terms, at levels suitable for both kids and adults, and next time we’ll see what happens when …
