Pythagorean Theorem Visual Voice Tour

I love it for the fact that he shows the actual usage of the theorem in our lives.

[bethpage89]

The Theorem refers to the squares ON the sides, not the squares OF the sides.

[elindred]

huh, i never saw the proof like that before. I'll have to remember that.

[amjPeace]

Pretty neat!

[nickharvey7]

Neat video!

[videogamesdude96]

im the only comment within 6 mouths lol

[findthemonthefloor]

read euclid.

[falconbird123456789]

welll all of that woulkd be true, except, the pythagorean theorem is to make a square out of a triangle using the sizes of b2 and c2, u cant make more triangles to make it, its simple if you do that

[zeb066]

the earth is not flat, so Pythagora's theoren does NOT apply to the map of Australia.

[Skillusion]

No, Earth is not flat, but distances can be curved ;).

[gnominKde]

never use paint...

[peepskarf]

its hypotenuse not HI-POT-EN-OOSE!! ND ITS A RIGHT ANGLED TRIANGLE NOT A "RIGHT" TRIANGLE

[LeyDrei]

he's right hypotenuse is pronounced that way and right angled triangles are called right triangles

[gorbidder]

cmon people this is grade 8 mathematics.

[lizzozzy]

i don't get  the square part and how that = c2....i understand how to find c on a normal triangle but the way you did it was confusing:(

[x2keithm3x]

He makes the original square by using c the hypotinous as the sides. So the aread that a squared plus b squared formed was the square c squared

[x2keithm3x]

Lol if the world was flat maybe but thanks so much for your example its so simple

[crazy650c]

Your second example showing the globe does not take into account the curvature of the earth...bad example.

[chris8649]

You are right, of course, given that the sum of the angles of a triangle on the surface on a sphere don't add up to a straight angle. I probably should have chosen another example, but then, if the student can figure out what is wrong with this one (which isn't per say, that the Pythagorean Theorem is irrelevant for computing net distances if you know the orthogonals, but that all of geometry needs adjusting for curved space), then perhaps some additional learning has taken place.

[chris8649]

btw, the first example has the same issue, now that I reflect on it...surface of a sphere and all that. Oh, well - it's so hard finding regular life examples for distances that don't end up being confounded by this positively curved planet thingie :)

[NNemisis99]

FIRST! An interesting way of thinking of the pythagorean theorem tho
