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.
