11.3- Perimeter and Area of Similar Polygons
Today we learned the relationship between the ratio of corresponding sides of similar polygons compared to the ratios of their perimeters and areas.
Tonight's homework is P. 740-742 # 5, 7, 12, 13, 17, and 28
You can see the gazebo question from class here: http://www.classzone.com/cz/books/geometry_2007_na/resources/applications/animations/geom07_ch11_pg739.html
Also, we will have our next cumulative test on Wednesday (Short Response) and Thursday (Multiple Choice). It will be two days just to ensure that we have enough time to finish the whole exam, even though it will not take both full periods. We will review the topics tomorrow in class.
