Who proved the Pythagorean Theorem?
Euclid provided two very different proofs, stated below, of the Pythagorean Theorem. Euclid was the first to mention and prove Book I, Proposition 47, also known as I 47 or Euclid I 47. This is probably the most famous of all the proofs of the Pythagorean proposition.
How did Euclid prove the Pythagorean Theorem?
In order to prove the Pythagorean theorem, Euclid used conclusions from his earlier proofs. Euclid proved that “if two triangles have the two sides and included angle of one respectively equal to two sides and included angle of the other, then the triangles are congruent in all respect” (Dunham 39).
When was Pythagoras theorem proved?
The statement of the Theorem was discovered on a Babylonian tablet circa 1900-1600 B.C. Whether Pythagoras (c. 560-c. 480 B.C.) or someone else from his School was the first to discover its proof can’t be claimed with any degree of credibility….Remark.

Who are Pythagoras Euclid?
In particular, most of the story of Pythagoras (500 BC) and Euclid (300 BC) is based on legend. Pythagoras founded a secret society whose mathematics was just one part of their activity.
How many proofs of Pythagoras theorem are there?
This theorem states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of each other sides square. There are many proofs which have been developed by a scientist, we have estimated up to 370 proofs of the Pythagorean Theorem.
How many proofs does the Pythagorean Theorem have?

What makes Bhaskara’s proof of the Pythagorean theorem so elegant?
Bhaskara’s Second Proof of the Pythagorean Theorem Now prove that triangles ABC and CBE are similar. It follows from the AA postulate that triangle ABC is similar to triangle CBE, since angle B is congruent to angle B and angle C is congruent to angle E. Thus, since internal ratios are equal s/a=a/c.
