### Pythagoras.

Thursday, February 19, 2009

Pythagoras was a UBER smart Greek mathmitician.
People were not sure if he was real or not ,
because there was no evidence of his exsistence.

Vocabulary -

Legs: Lines that come out of a right angle , with one going up and the other to the side.
Hypotenuse: The longest side of the triangle and opposite of the right angle.

R.A.T.: Right Angle Triangle.

Greek: Someone who comes from Greece.

Theroum: A Theory that can be proved.

This vocabulary is all connected by the Pythagorean theorum.

This artifact is a square. The lines shown are lines of simitry.
The lines of simetry say that all 4 sides are equal. 2 Right Angle Triangles make a square.

This artifact is a right angle triangle. I has 3 sides. side A & side B which are the legs. Side C which is the hypotunuse and also the longest side.

This is Harbecks Toy INC board game. It is made up of a square and 4 identical triangles. The center square has an area of 225cm². We have to figure out what the perimeter of the game board is.

So first we need to find out what the square root is , and that its 15cm. Now we know each of the legs is 15cm. Now we need to solve for the hypotenuse. So this is how we would do it ,
( 15x15 ) + ( 15x15 ) = c²

225 + 225 = c²

450 = c²

Here are my Pythagoras Videos.
