MPM2D - Day 73: Cosine Law (day 2)

We jumped right back into cosine law today with this example:

They are really doing well with this. We went over what it means to solve a triangle before they worked on the next question.

As we had not practiced using the cosine law to solve for an angle very much, we did a couple of those types of questions.

They seemed to be getting the hang of seeing when they could use sine law and when to use cosine law. We talked a little about the upcoming summative where they will need to show multiple skills, not the same one over and over.

That example flowed nicely (pun intended) into answering "When do I use what?". Here is the link to the page with the following flowchart. I like its simplicity.

Here is today's homework.
