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. (0B has seen theirs). 2nd and 3rd period will take the open response questions at the beginning of class on Oct 24.
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.
If I have not graded your construction unit review assignment, please show it to me in class on Oct. 24.
HW #1 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 #1 - pp 85-86:1-14,21-23. It is OK to do the entire assignment on graph paper if you wish.
Quiz on Tues-Wed (October 29-30) at the end of class, 18 pts.
Notes from pp 79-81 should be borrowed from someone in the class if you were absent. You should read these pages carefully.
