Pythagoras's Theorem

(mathematics)
The theorem of geometry, named after Pythagoras, of Samos, Ionia, stating that, for a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. I.e. if the longest side has length A and the other sides have lengths B and C (in any units),

A^2 = B^2 + C^2

This proof is worth revisiting every year, being aesthetically lovely to behold, as is Baskhara's implicitly algebraic proof of Pythagoras's Theorem, which uses a diagram of a hypotenuse inner-square inside a larger square made with four other triangles: consider these two alternatives (see Figure 3).
True education should involve instilling standards and principles in our young - a bit more useful to most of them than being able to understand Pythagoras's theorem.
The distance between two words (or points) is simply calculated using Pythagoras's theorem.
Pythagoras's theorem yields the square root of [25.sup.2] + [25.sup.2] = 1250, or 35.36.
It is common for estimates of several lengths to be made in such cases, but an elementary application of Pythagoras's theorem shows that the amount of ground lost is considerably less.
The facile point the programme was determined to labour was that players who wouldn't know Charles Dickens from Alan Dickens, who didn't speak at least three languages or weren't familiar with Pythagoras's Theorem were somehow destined to "struggle under the immense pressure" of being paid a huge amount of money to kick a ball about.
I could spell Pythagoras's Theorems but could I hell understand them.
