This self checking worksheet solves the acute and the obtuse triangles of the SSA case of the Law of Sines. The students are to find the three missing pieces of the acute triangle, then find the three missing pieces of the obtuse triangle using the original information. When finished, they students will find an interesting thought.
My students were having trouble with this, so I made this worksheet for them. You should have heard them complain when they saw there were FOUR WHOLE problems on the worksheet. LOL I told them they were in higher math when they complained about four problems. (Then I thought: Complain about only four of these???)
