Hi all,

Hope you had a great Thanksgiving! In week 11, we reviewed for the test and had our test 3 on Thursday. Remember to regrade for more points!

On Tuesday, we started talking about angles, degrees and triangles, these will be the basis for trig functions, starting from next week.

For what we learned on Tuesday, make sure you understand how to compute complementary and supplementary angles, how to compute the length of edges in a right triangle. Similar triangles are triangles of the same shape, and always have the same angles. Therefore their corresponding edges have lengths of a fixed ratio.

Next week, we will introduce trig functions in right triangles and Cartesian planes. In right triangles, they are really just ratios of the length of edges.

Alright, that is it for now. Let me know if you have more questions!
