Pythagoras Theorem: This article explains the concept of Pythagoras Theorem and its converse. Know the definition, formula, proof, examples and applications of Pythagoras Theorem.

Pythagoras' famous 2,000-year-old theorem, summarized neatly as a 2 + b 2 = c 2, means that you can work out the length of any side of a right-angled triangle as long as you know the length of the ...

But it wasn't. The 2,000 year-old theorem states that the sum of the squares on the legs of a right triangle is equivalent to the square on the hypotenuse, or the longest side of a right triangle.

Pythagoras’ theorem can then be used on either of the two right-angled triangles. The 3.4 m length becomes the hypotenuse so should be labelled 𝒄. The height is 3 m, and can be labelled as 𝒂.

The Pythagorean Theorem , which states, ``The sum of the areas of two squares on two sides (a, b) is equal to the area of the square on the hypotenuse (c),'' is also known as the ``Pythagorean ...

Pythagoras’ theorem is always true for right-angled triangles. 130 is not the same as 121. As 𝒂² + 𝒃² does not equal 𝒄², the triangle cannot be a right-angled triangle.
