First, take the Chapter 6 Quiz! If you need a few minutes to study, we can take some time to do that.

Read 7-1: Geometric means can be written as proportions, or as square roots. Make sure you understand both! This section can be confusing - ask me if it's not clear!

Unable to find food, Sally tries to sleep in the stable again, and ponders the roof (a right triangle with the right angle at the top), with its single vertical support (an altitude). If the roof is 13 feet wide, with 9 feet on one side of the support and 4 feet on the other side, how tall is the support?

In 7-1, work problems 6-12 even (for 12, draw it – this is ONE triangle, you just need to move the altitude), 36, 38, 42, 43, 50, 58-66 even. Finally, do the activity on p. 349 and answer questions 1-3 (yes, that means you'll do the activity twice – you can draw squares on your assignment paper, or get a separate sheet – ask me for a ruler if you need one)

Extra Credit # 28, 33, 34, 44, 45 (draw this out with a specific triangle, and remember the rules for similarity)
