Math Blog 817 (2008): Pythagoras

Pythagoras

Friday, February 20, 2009

We were given an assignment about a Greek mathematician name Pythagoras. Pythagoras was "uber smart". He was best known for the Pythagoras Theorem.

We were given 4 objects that linked with each other in a way. The 4 objects were Pythagoras, a square, a right triangle, and a equation. To me, the pictures are all linked to his Pythagoras Theorm. We were given some important vocabulary. The words were legs, hypotenuse, R.A.T, .
greek, and theorem.

Okay firstly you people have to check what is (A) and (B)... Simple do the square root of it, you should have 15 as an answer. To figure out C you must do the (A) and (B) square first so it'll equal 225 for both... Then square root the 450 which gives you the answer 21.213

Okay you see how theres a question mark there,.... This is how you solve it in my eyes of point of view....

Here's the formula... c(2)-b(2) =a(2)

The numbers that are showned are pretty straight forward... 10(2)-8(2)=c(2)

now just square it!!!..100-64=c(2)

all equals 36=c(2) then use the square root on it...!...

And the final result is 6 on both sides.

I will try to define the words now.
Legs:
- Legs can be located in right triangles. There are 2 legs that come out of the 90* angle in the triangle. The legs are also the shortest sides of the triangle. Legs are shorter that the hypotenuse.

Hypotenuse:

- Hypotenuse can be found in triangles. The hypotenuse is always the longest side of the triangle and is opposite of the right angle.

R.A.T:

- R.A.T is just a short version of Right Angle Triangles.

Greek:

- Someone from Greece.

Theorem:
- It is a statement in math that has to be proven correct or true. eg. The Pythagoras Theorem was a2xb2=c2.

Here are some pictures to explain hypotenuse and legs.

Now I am going to talk about the right triangle. The right triangle has a 90* angle. Together the whole triangle is 180*. The other 2 angles you will have to measure to find out. Here is a picture showing a right triangle and some stuff about it.

Now to talk about the square. The square has 4 equal sides which means all the sides are the same length. You can show it is a square by using lines of symmetry. Squares have 4 90* angles. Together the whole square is 360*. I will show you a picture of what i just explained

Rectangles can be deceiving sometimes, but they are not. Rectangles are very similar to squares. They both have 4 90* angles are both 360*

Now I'm going to show you how to find area in squares. I will be putting down 2 examples.

Now to do some tricky stuff. We were given a yellow paper that we had to put some very important information on. For homework on Friday we had to put them in. I didn't really understand it perfectley, but I still got it finished. Now to show you the goods.
