Today’s Lesson
- Quiz Debrief. 11 out of 20 students wrote the quiz. Two more had authority to postpone it by one day. The mean (average) mark was 96%, so really easy test I guess! The median mark was 120%, over half those who wrote got 120%, sweet (I was allowing ,this one time, a mak of 120% for those who needed it!)

- Finish Up Assgt G-5 pg. 3 Determine Angles Using Cosine Law
- Lesson Support Video Playlist: Find an angle using cosine law.
- Introduce Sine Law.
- Unit G Notes pp. 14- 15
- Lesson Support Video(s): Sine Law.
- Assignment G-6 Sine Law. (due:<15 May)We will do some more together in class on Monday.
- With the Sine law and the Cosine Law you can technically do a brain dump on SOH CAH TOA since those two laws work for every triangle, not just Right Triangles. However, you will find SOH CAH TOA is quicker and more effective if just calculating a Right Triangle
- Update: Handed out some practice Euclidian Geometry Questions (not handin)
