Pythagorean Theorem.... who remembers that from school?
I don't think I ever truly got it until now.
A finished up Teaching Textbooks 7 with a study on Pythagorean Theorem and finding the missing side of a triangle.
For a visual we used cheese crackers.... Lightbulb!
It clicked for both of us.
I always new a squared + b squared= c squared but WOW!
Sometimes it just takes a visual.
