Pythagoras

Pythagoras or Pythagoras theorem is one of the most useful theorems in geometry and math. Pythagoras theorem allows many calculations to be made about triangles. The man who found Pythagoras theorem was the Greek philosopher and mathematician, Pythagoras.

Pythagoras theorem

Pythagoras theorem is a simple rule about the proportion of the sides of right triangles. The Pythagoras theorem states that:

" the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides of the right triangle."

The illustration of Pythagoras theorem

Right triangle in pythagoras theory

In a right triangle, a² + b² = c² . This is also known loosely as Pythagoras formula.

Suppose a = 4, b = 5, then:

c² = 4² + 5²  = 16 + 25 = 41

c = the square root of 41 = 6.403124.

Who was Pythagoras?

The Pythagoras theorem is invented by Pythagoras. Pythagoras (ca. 582 - ca 497 B.C.) was a Greek philosopher and mathematiccian. Pythagoras' ideas influenced great thinkers throughout the ages. Pythagoras is well known to math students for the pythagoras theorem.
