Our last unit of the year is about using the similarity of right triangles to find information. It is the beginning of all you can do with the topic of Trigonometry (you would be amazed at how useful this topic is in all branches of math and science). We don't have a lot of time for this unit so we are only covering selected sections of chapter 9.
