Today our big goal was to find our best personal strategy for rotation and practice it. Also, we did an investigation to come to an understanding of the definition of congruent geometric figures in terms of rigid motion:
Congruent geometric figures are figures that will map exactly on top of each other through one or a sequence of rigid transformations.
The rotation warm-up and the two investigations we did in class are attached below.
I checked HW #2 for a grade (4 pts) and we corrected it.
Students also got the see their fall finals and the original to understand their mistakes.
HW #3 is a handout attached below. On Problem 1, the parts a-d state to go back to the original shaded (black) triangle for each transformation. It is NOT a composition of 4 transformations. EACH GOES BACK TO THE ORIGINAL.
The first attachment contain both the rotation warm-up and the homework.
