# FAQ: What Did Pythagoras Say When He Was Confronted By The Square Root Of 2?

## What is the Pythagorean Theorem explain how the Pythagorean theorem may be proven using squares How can the Pythagorean theorem be used to find distances on a plane?

Explain how the Pythagorean theorem may be proven using squares. How can the Pythagorean theorem be used to find distances on a plane? The Pythagorean theorem addresses the sides of a right triangle, it states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.

## Who discovered the square root of 2?

The proof of the irrationality of root 2 is often attributed to Hippasus of Metapontum, a member of the Pythagorean cult. He is said to have been murdered for his discovery (though historical evidence is rather murky) as the Pythagoreans didn’t like the idea of irrational numbers.

## What did Pythagoras discover?

In antiquity, Pythagoras was credited with many mathematical and scientific discoveries, including the Pythagorean theorem, Pythagorean tuning, the five regular solids, the Theory of Proportions, the sphericity of the Earth, and the identity of the morning and evening stars as the planet Venus.

## How did Pythagoras prove the Pythagorean Theorem?

According to legend, Pythagoras was so happy when he discovered the theorem that he offered a sacrifice of oxen. The Pythagorean Theorem states that: “The area of the square built upon the hypotenuse of a right triangle is equal to the sum of the areas of the squares upon the remaining sides.”

## How do you solve A2 B2 C2?

The formula is A2 + B2 = C2, this is as simple as one leg of a triangle squared plus another leg of a triangle squared equals the hypotenuse squared.

## Is Pythagorean theorem only for right triangles?

Pythagoras ‘ theorem only works for right -angled triangles, so you can use it to test whether a triangle has a right angle or not. In the triangle above, if a 2 < b 2 + c 2 the angle is acute.

## Is 2 a perfect square?

Answer: YES, 2 is in the list of numbers that are never perfect squares. The number 2 is NOT a perfect square and we can stop here as there is not need to complete the rest of the steps.

## Why is the square root of 2 special?

The square root of 2 is “irrational” (cannot be written as a fraction) because if it could be written as a fraction then we would have the absurd case that the fraction would have even numbers at both top and bottom and so could always be simplified.

## How do you prove √ 2 is irrational?

Proof that root 2 is an irrational number.

2. To prove: √2 is an irrational number. Proof: Let us assume that √2 is a rational number. So it can be expressed in the form p/q where p, q are co-prime integers and q≠0. √2 = p/q.
3. Solving. √2 = p/q. On squaring both the side we get, => 2 = (p/q) 2 => 2q 2 = p 2 ……………………………..(1)

## Who is the father of mathematics?

Archimedes is known as the Father Of Mathematics. He lived between 287 BC – 212 BC. Syracuse, the Greek island of Sicily was his birthplace.

## Who invented math?

Beginning in the 6th century BC with the Pythagoreans, with Greek mathematics the Ancient Greeks began a systematic study of mathematics as a subject in its own right. Around 300 BC, Euclid introduced the axiomatic method still used in mathematics today, consisting of definition, axiom, theorem, and proof.

## Why did Pythagoras not eat beans?

Pythagoras the vegetarian did not only abstain from meat, he didn’t eat beans either. This was because he believed that humans and beans were spawned from the same source, and he conducted a scientific experiment to prove it. To eat a bean would therefore be akin to eating human flesh.

## Where is Pythagoras theorem used?

The Pythagorean Theorem is useful for two-dimensional navigation. You can use it and two lengths to find the shortest distance. … The distances north and west will be the two legs of the triangle, and the shortest line connecting them will be the diagonal. The same principles can be used for air navigation.

## When was Pythagorean theorem invented?

Pythagorean Theorem. The Pythagorean theorem was first known in ancient Babylon and Egypt (beginning about 1900 B.C. ). The relationship was shown on a 4000 year old Babylonian tablet now known as Plimpton 322. However, the relationship was not widely publicized until Pythagoras stated it explicitly.

## What does Pythagorean mean?

: a theorem in geometry: the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.
