TOPICS: Right Angle     Leg     Legs     Pythagoras Formula     Hypotenuse     Right Triangle   Next we’re going to look at the formula of the Pythagorean Theorem, because of all the knowledge that Pythagoras left us regarding the proportions of the sides of a right triangle, without a doubt the most important is the…

### Pythagorean Theorem Proof (Euclid)

TOPICS: Euclid’s Proof     Theorem Proof     Prove Theorem Euclid was a Greek mathematician and geometrician who lived from 325 to 265 BC and who formulated one of the most famous and simplest proofs about the Pythagorean Theorem. What Euclid demonstrated was that the area of the square that has the hypotenuse…

### Pythagorean Theorem: Concept and Uses

TOPICS: Pythagorean Theorem Concepts     Uses of the Pythagorean Theorem   To really understand the Pythagorean Theorem we have to be clear on some concepts. For example, it only applies to right triangles; in other words, triangles that have a right angle. We also have to know what the names given…

### What Is the Pythagorean Theorem?

Before we talk about the definition of the Pythagorean Theorem, we should remember two basic ideas from mathematics and specifically geometry: The definition of a right triangle: in simple terms, a right triangle is a triangle that has one of its internal angles measuring 90°. The sides of a right…

### Definition of the Pythagorean Theorem

Although the Pythagorean Theorem was discovered many, many years ago, we continue to be surprised that even today there are more and more diverse fields that require, in one way or another, knowledge of this theorem. Pythagoras was a philosopher and mathematician in ancient Greece and among his many discoveries…

### What is the Pythagorean Theorem?

### Pythagorean Theorem Proofs

The most well-known and widely used proof of the Pythagorean Theorem is the one which relates the areas of the squares that have, as their sides, the two legs and the hypotenuse of the triangle. We have referenced this proof in an older post where we have also provided a…
