Pythagoras

Pythagoras was a Greek mathematician. He was the first vegetarian. He proved
the Pythagorean Theorem. He is known as "the father of numbers".




This triangle is Right Angled or R.A.T. The letter "A and B" are called legs.
And the letter "C" is called Hypotenuse.




This Square is quadrilaterals. All side of square are equals 90 degrees.



I showing you 2 example of theorem.
Here is the first example of Pythagoras Theorem.



a^2+b^2=c^2
a^2+8^2=10^2
-8^2 -8^2
a^2=10^2-8^2
a^2=100-64
a^2=36
a=6
a+a=|----|
6+6=12mm


Here is the second example of Pythagoras Theorem.






a=225cm
a=225
a=16
length and width is 15.
The perimeter of the central square is 60.
Means A and B is equal to 15.
a^2+b^2=c^2
15^2+15^2=c^2
(15x15)+(15x15)=c^2
225+225=c^2
450=c^2
21.21=c^2
P=21.21+15+15
P=51.21
Perimeter of each triangle is 51.21

P=60+51.21(4)
P=60+204.84
P=264.84
The perimeter of board is 264.84.
