Today was our second day of transformations.
Our focus was translation.
We learned that translating maintains shape and size of a geometric figure, so it is a rigid transformation.
We translate right or left and up or down along a translation vector. We can describe in words (like move the triangle 5 to the right and 3 down) or as a coordinate rule (x+5,y-3) or as a vector.
We practice several different translation problems in class, which should make the homework (attached below) seem a lot like what we did in class.
We also shared homework answers about rigid and non-rigid transformations, types of symmetry, and rotating, translating, and reflecting on square dot paper.
No assessment until after Thanksgiving. No homework over the break.
