Talk:Ideas in Geometry/Instructive examples/Section 2.4:

Hey, I think you did a really good job at explaining both the picture and the steps needed to figure out how to solve the problem. I think it was very helpful that you talked about two different methods of finding the solution so people who do not understand will be able to pick the way that works best for them. Also your explanations were easy to follow. Nice job!

I think you did a great job explaining yourself in terms of the picture and made it clear what the question was asking for. I understood completely how to do the problem just from your explanation.

The picture was very neat and practical, but is there a reason why the formula works? I understand that it does work, but how and why? Is there a mathematical rule or theorum that can be used? Rehus1 01:58, 3 November 2010 (UTC)
