1. Good Job Louis! Your pictures were perfect. Your scribe was very neat and easy to read. But next time, you should of changed font colours even more.. But over all good job!

2. Jomer, you did a good job. Your information was good, and would easily explain the answers to people who needed to double-check their answers. But... for 1)a, it should be 'what *is* the area of...'. Also, to get the 'squared' sign, use alt+253. Like this: a²+b²=c². Good post.
