What and Why
- Bob Allen
Click and drag point A around. Click and drag point B around. Did your sketch break?
What kind of triangle did you create?
How do you know? What did you measure? Are the measurements on your sketch? If not, please include them.
Now, how do you know this will work every time? Imagine a segment AB the size of the galaxy. Or imagine segment AB the size of a molecule. Convince me that you will always get the type of triangle you identified. Hint: You made three circles. How do segments AB, AC, and BC relate to each other and those circles? What are they?
