I'll just give a quick run down, I won't go into too much detail.

I am in the 7th grade, all of my class are Pre-AP, which means "Pre-advanced placement". Basically for really smart kids. We take 8th grade tests instead of 7th for the STAAR, which is a state test so we can go to the next grade.

I've been studying really hard lately and I just don't get the Pythagorean Theorem. I get the basics of it, but when it comes down to it, I really suck at it.

The STAAR is in April. It's January...

Can anyone help me out here?

Don't worry. Pythagorean Theorem is really simple.
Remember the formual a^2 + B^2 = C^2
A and B are the 2 legs and C is the Hypotenuse.
A hypotenuse is the side across from the right angle.
You can plug in any two values that you have and solve.
I can help you further, but I need to know where you are struggling in particular.

Construct the proof yourself.

well then...

just wait for 10th grade...
Le wild 3d trigonometry appears.

Anyway, just ask me on skype if i'm online.

My math exam is tomorrow. I'm struggling with it XD those cos, sin, tan things.

It's more than that. Like proving and stuff. We also make use of tan sin cos hexagon. Speaking of which... I should be studying now.

I see you speak Anti-Dubish.

Pythagorean Theorem.
He states, that a^2+b^2 equals to c^2
This is used to find the missing length of one of the sides on a triangle.
(If your triangle is 90 Deg then you can easily find the Volume and so on.)

- Then you can go on:
The sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse. (The word comes from the Latin sinus for gulf or bay,[1] since, given a unit circle, it is the side of the triangle on which the angle opens.) In our case
\sin A = \frac {\textrm{opposite}} {\textrm{hypotenuse}} = \frac {a} {h}.
Note that this ratio does not depend on the size of the particular right triangle chosen, as long as it contains the angle A, since all such triangles are similar.
The cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse: so called because it is the sine of the complementary or co-angle.[2] In our case
\cos A = \frac {\textrm{adjacent}} {\textrm{hypotenuse}} = \frac {b} {h}.
The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side: so called because it can be represented as a line segment tangent to the circle, that is the line that touches the circle, from Latin linea tangens or touching line (cf. tangere, to touch).[3] In our case
\tan A = \frac {\textrm{opposite}} {\textrm{adjacent}} = \frac {a} {b}.
The acronyms "SOHCAHTOA" ("Soak-a-toe", "Sock-a-toa", "So-kah-toa") and "OHSAHCOAT" are commonly used mnemonics for these ratios.


(A triangle has A B C and a b c. I'm in tenth grade, exams are close up, and shit I don't even get sine tangens or cosine, you know what? I don't give a fuck. xD)

happens...

have you done the cosine rule and the sine rule and stuff?
