We just completed our first block of the new unit on Similarity. We answered some questions to help us think about what similarity is: What does it mean for two things to be similar (not in math)? What do you know about similar figures in mathematics? And later: Are all circles similar? Are all squares similar? Are all rectangles similar?

Grades were taken over HW #6 (triangle unit review) for 6 pts and HW #7 (4 pts on p 561-2).

We went over homework and wrote a definition and sketches in Geometric Truth for Similar Polygons from the top of p 565.

After looking at examples and practicing testing figures against the definition, we previewed our homework, went over HW #7, and then did the Dilation Investigation on p 566 to discover that dilated polygons do in fact meet the definition of similar polygons.

Glue the investigation into your In-Class section of your notebook.

HW #8 - p 568-9: 1-15. On problems where you are finding missing sides, write proportions to solve.

Tests will be viewed next block. If you have not taken your test yet, IT MUST BE DONE BY ADVISORY ON TUESDAY.
