This took me about two weeks to complete! Don’t know why, it’s not that many slides. I drew lots of Geogebra diagrams. There’s a worksheet with 15 questions.
I made this for a class with really strong prior attainment. I think I could probably do with some questions where they have to pick the correct calculation. I have added 4 questions that can be done on whiteboards to kick off the lesson, though.
There’s also a chat on when to use the sine rule.
And some more fun questions!
There’s a second lesson here, too. Using the sine rule. (although I could really do with some more questions here!)
And the ambiguous case
