Today we reviewed how to use a protractor and learned what "normal" really means. These will be very helpful in our new unit: geometric optics.
Most people finished their homework in class, but it is also below - Angles and Normals .
Also PLEASE buy yourself a protractor! I only have 10 for the whole class!
***Update*** Now we have nine. Someone stole another.
