Thread: 8th grade Pythagorean Theorem

1. 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?

2. 1 with hypotenuse unknown
I'm standing 20 feet from a 50 foot tall building. How far am I from the top of the building?

Here is a nice diagram to model the pythagoreum theorum, although usually the formula is $\displaystyle a^2+b^2=c^2$ where side BC=a, AC=b, and AB=c. You can move the red points.

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

Tell me if this helps.
