    8th grade Pythagorean Theorem

    I am trying to help my son w/homework, and I really don't have a clue about this, sad, I know.

    I thought if I could understand it, I could help him understand it.

    THe subject is Pythagorean THeorem.

    He needs to come up with 3 real world scenarios w/representation of R triangles....1 w/Right triangle base lenght known, 1 w/height unknown, and 1 with hypotenuse unknown?

    I don't even know how to explain to him Pythagorean Theorem, I can hardly spell it!

    Help?

    Sorry, your Web browser is not Java compatible. This prototype will not be of much interest to you.
    Here is a nice diagram to model the pythagoreum theorum, although usually the formula is a^2+b^2=c^2 where side BC=a, AC=b, and AB=c. You can move the red points.






    The pythagoreum theorum states AC^2+BC^2=AB^2 although it is written more commonly as a^2+b^2=c^2 where a is the side opposite angle a (in the diagram).
    "c" must always be the hypotenuse.





    Tell me if this helps.
