Reflection: Intervention and Extension Review of Solving Triangles Day 2 of 2 - Section 2: Review Activity


As students were working on determining the solutions for question 4 this question came up: "When you have 2 solutions is the first solution always going to be the triangle with the largest area?"

This is an interesting observation for a student. I asked why do you think this is the case. The student stated that the second solution happens when the opposite side swings in closer to the known angle which makes this triangle have less area.

This student continued to look at the relationship and wanted to know if the larger triangle's area is twice the smaller angle. I told the student to check and see if it was true. I continued to let the student explore by saying "If you find this is true can you justify the result in general?"

This allowed students who needed to think deeper the opportunity to go deeper. The student had some interesting ideas and I was happy the student was questioning.
