### Pythagoras Theorem

9:33 PM

We were given 2 weeks to explain the Pythagorean Theorem. This is what I have learned in that time.
Artifact #1
Pythagoras was an Greek mathematician. He was born in Greece around 500 B.C.E and he had lived close to 100. Pythagoras died around 500 B.C and 490 B.C. He was the world's first vegetarian. He thought when you die you were re born as a animal, so he thought he would be eating his friends if he ate a animal. He proved the earth was round. He created the Pythagorean Theorem and proved it so it was named after him. He was considered farther of geometry and music. And some people thought he was a lunatic.

You need to know these key words:

Legs: Each triangle always has 2 legs. The legs will always be shorter then the hypotenuse. Is connected by the right angle.
Hypotenuse: The longest side of a triangle. Is across the right angle.
Theorem: A math statement that has been proven to be correct or true. This Theorem was
A² + B² = C².
R.A.T: Right Angle Triangle
Greek: People who lived in Greece, Pythagoras was o

His Theorem were...

This is example of the theorem.

Artifact #2

R.A.T. is an abbreviated form of Right Angle Triangle, which is a triangle that has a 90° angle.

The legs are the shorter sides and the hypotenuse is the longer side.
Both Legs add up to 90 degrees
Theta and Beta are in the corners
Theta and Beta add up to 90 degrees
A Right Angle Triangle adds up to 180 degrees

Artifact #3

A square is a certain amount of right angle triangles combined.

If you were to divide a square in half you would get a triangle with 90 degrees.
There are four 90 degree angles in a square, if you add them together you would get 360 degrees.
A square has 4 even sides and can be identified by the little ticks on the squares sides.

A2=C2-B2
A2=10 squared -8 squared
A2= (10x10)-(8x8)
A2=100-64
A2=36
/A2=/36
A=6
A=6
A+A= ?
6+6=12mm

Here is a video explaing some of this stuff.

This is another video showing how you can get b or a if you have a/b and c.
