Talk:Ideas in Geometry/Instructive examples/Proving Sets Equal, Section 2.1

I like your pictures of the answers, but I think it would be best to have an actual discussion with words about your problem. You should write the steps out that you did with the pictures so students that have never taken this class can follow along also. Also, you should write the definitions that one may need to know in order to solve this problem, such as what a union is and a intersection is in the beginning of your discussion.
