Study Guides -
Each section in the book has a Study Guide which if you print **prior** to going over in class and filling it in, you will be prepared. The problems on each Study Guide will be gone over in class.

Section 5.4:
Section 5.4 is on angle sums and we covered these last year, however, to remind you a bit about what you already know I thought I'd put some notes here. Last year we worked with degrees when we used these formulas and this year we are working with radians. Remember last year that we divided the angle into the sum of two angles that we knew the value of, which was easy when the angles were nice numbers but then when we got some angles (usually multiples of 5 degrees) we found that if we subtracted out a multiple of 45 degrees it worked. So, when you get angles that are 12ths, etc. you need to subtract out a multiple of pi/4 and usually what remained was an angle you recognized! Remember this when doing this section. Also, check out the video below for this section!

Test Area -
This is where you will find the test on the material prior to due date, if it is a Take-Home test! I will announce in class the date when tests are available online and you are responsible to print them out, complete them and hand them in on or before the due date.


 * Chapter 5 Test - Will appear here when assigned.**
