I knew I had a lot in yesterday's lesson and I had today's lesson as a day of processing and practicing. We were back at the board to do special right triangle trig with special right triangles and points on a plane. I think it went okay. I think they are getting the ratios now.
Here is the powerpoint lesson: Practice Right Triangle Lesson
Here are the board problems: Practice Trig Board
Here I asked them to draw and label a 30:60:90 triangle. Then, I asked them to find sines and tangents:
Here was same triangle, different student, different questions:
(These students wanted to be in the picture.)
Then, I switched to the 45:45:90 triangle: We also looked at writing inverse:
Here we looked at both special triangles together:
We were running out of time, but we graphed the magnetic graph and put a point on the coordinate plane to introduce finding the ratios given a point and the idea of a reference angle:
Tomorrow: Law of Sines
This is a HEAVY unit!
