Pythagorean Theorem Video

Today we started reviewing radicals, and talking about Pythagorean Theorem. I know they've seen it before, but they still need help on the harder problems. I found this cool, short video that I showed a few times in a row until they understood it. It was a fun discussion on what he was trying to do.

Then we built up their skills with individual problems of varying difficulties:

(the terms listed are "a", "b", and "c" for a right triangle with hypotenuse "c"):

1. x, 4, 10
2. 3, 9, x
3. 2*sqrt(3), x, 4
4. x, 3, sqrt(17)
5. x, 3x, 20
6. some sort of trapezoid with 90 degree angles on one side.

Anyway, I just wanted to post about the water video. Done. Dinner.
