Today is our first block of the Rigid Transformation unit. If you have not finished or taken the Construction Unit Test, you need to come by and talk to me ASAP. Tests will be graded and viewed in class on Oct 24-25.
Rigid transformations bring together algebra and geometry in an interesting connection. Our big idea is that a rigid transformation in a plane creates an image that is congruent to the original pre-image (maintains distance and angle when moving).
We created notes from reading in class today (copy attached). We also did investigations 1 and 2 from pp 81-83 in the textbook. And we practice rotating 90 degrees on a grid.
All grades through HW #1 are caught up and posted. Check through HAC to make sure I have not made any mistakes.
HW #2 needs graph paper and a small piece of patty paper. You can print off graph paper by googling "graph paper PDF". Waxed paper or tracing paper will work for patty paper.
HW #2 - pp 85-86:1-14,21-23. It is OK to do the entire assignment on graph paper if you wish.
Quiz on Fri-Mon, 18 pts, at the end of class.
