Our in-class time was devoted to several activities that should have increased mastery over 1) rotating around a point, especially not the origin, 2) reflecting across a horizontal or vertical line (not an axis), 3) rotating 270 degrees (same as 90 in the opposite direction), and 4) describing a sequence of rigid transformations to map one geometric figure directly onto another (congruence).
We began by adding reflections to previous block's rotation practice (attached below). Then we went over this and homework before doing the Aussie Rotation Activity (attached below). We then did three problems practicing describing a sequence of rigid transformations to determine congruence (attached). HW#4 (attached below) is a worksheet due Block 5. Come by to get graph paper if you need it.
Read about "glide reflection" on p 376 of your textbook.
We finished with the quiz.
In Block 5, you will receive your review worksheet and test topics as well as doing some more practice with multiple choice, rotation, reflection, symmetry, and different ways of saying the same thing.
Again, the test is Tues-Wed, Jan 24-25. You will have homework due Jan 26-27 over Pythagorean Theorem to start the next unit.
