# Contribution Of Pythagoras

Education News | Apr-17-2022

Pythagoras was an Ionian Philosopher and a brilliant mathematician. He was born in the 6th Century BC on the Greek island of Samos. He had followers called "Pythagoreans" who were either the 'Mathematekoi' (learners) or the 'Akousmatics' (listeners). He was one of the most important mathematicians who believed that everything could be reduced to numbers that had their characteristics. He also considered 'Geometry' to be the highest form of mathematical study because through Geometry he can explain the real world. So let us now have a look at some of his major contributions to the mathematical world:

1) He discovered that in music, by beating strings tones are produced which are in a certain ratio and can be represented in whole numbers. This observation was extended to other musical instruments and hence, he was the one to open the gate of the musical world to us.

2) The 'Angle Sum Property Of Triangle' was discovered by Pythagoras only when he proved that the sum of all angles of a triangle is equal to 180°.

3) He even contributed to the discovery of "Tetractys" which was a mathematical magic pyramid.

4) His contributions were not limited only to triangles rather he also contributed to the "Polygon Angles" where he stated that the "sum of interior angles(n) is: 2n- 4 right angles and the sum of exterior angles will be equal to 4 right angles", which means 4 right angles subtracted from 2n then adding exterior angles will be equivalent to four right angles or simply 360°.

5) Lastly, the most famous contribution for which Pythagoras is popular worldwide is the discovery of the "Pythagoras Theorem" which applies to all 'Right Angled Triangle'. In the theorem, he stated that "the sum of the square of both Base and Height will be equal to the square of Hypotenuse of a Right Angle Triangle". This theory was a massive achievement in his career which even unlocked many treasures of mathematics out of which Trigonometry is the most prominent.
