## What is Pythagorean theorem in simple words?

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

## What’s another word for Pythagorean Theorem?

In mathematics, the Pythagorean theorem—or Pythagoras’s theorem—is a relation in Euclidean geometry among the three sides of a right triangle.

**What does the word Pythagorean mean?**

Pythagoras was the first person to call the universe Cosmos, describing it a ‘kosmos. ‘ The Greek word means ‘an equal presence of order and beauty.

### How do you explain Pythagorean Theorem to kids?

The Pythagorean Theorem describes the relationships between the sides of a right triangle. The square of the hypotenuse, the side opposite the right angle, is equal to the sum of the squares of the two sides. The formula is a2 + b2 = c2.

### What is the history behind Pythagorean theorem?

The Pythagorean theorem is a mathematical theorem named after Pythagoras, a Greek mathematician who lived around the fifth century BCE. Pythagoras is usually given the credit for coming up with the theorem and providing early proofs, although evidence suggests that the theorem actually predates the existence…

**What is the importance of the Pythagorean theorem?**

Pythagorean Theorem is important because you can find out if the triangle is acute, obtuse or a right angle triangle. The Pythagorean Theorem can also help you find missing side lengths of a triangle. Builders use the Pythagorean Theorem to help keep right angles and build houses, roofs, stairways etc.

## How was Pythagorean theorem found?

Around Two thousand five hundred years ago, a Greek mathematician, Pythagoras , invented the Pythagorean Theorem. The Theorem was related to the length of each side of a right-angled triangle. In a right-angled triangle, the square on the hypotenuse, the side opposite to the right angle, equals to the sum of the squares on the other two sides.

## Why does the Pythagorean theorem work?

This works because of the distance between the hypotenuse of the triangle is directly equal to the two square on the outside. In reality, there are many applications for the Pythagorean Theorem. One of the most useful applications of the theorem is using it to find the distance between two cities.
