1st Artifact:

Pythagoras was born between 580 and 572 BC, died between 500 and 490 BC. He was a Greek mathematician. Pythagoras was the first vegetarian. He is best known for the Pythagorean theorem, which bears his name. Known as "the father of numbers".

Some important vocabularies:

  • Legs -Short sides (a or b) of the Right Triangle that make the 90°.
  • Hypotenuse -The longest side of the right triangle.
  • R.A.T.-Right Angled Triangle, have 90° angle.
  • Greek - are a nation and ethnic group native to Greece, Cyprus and neighbouring regions who can also be found in a plethora of Omogenia communities around the world.
  • Theorem -may be taken to mean a formula that can be derived according to the derivation rules of a fixed formal system. The statements of a theory as expressed in a formal language are called its elementary theorems and are said to be true.

2nd Artifact: Right Triangle

3rd Artifact: Square/Rectangle

1st Proof:

a²+b²=c²

  • 6²+4²=c²
  • (6x6)+(4x4)=c²
  • 36+16=c²
  • 52=c²
  • √52=√c²
  • 7.211=c

2nd Proof:

Problem 1:

Problem 2:

Today in class we Discussed about the Pythagorean Theorem.

RIGHT TRIANGLE:


SQUARE:

  • There are Four 90° in square and all in all there are 360°.
  • Square is a quadrilateral.


  • a² +b² = c²
  • (a●a)+(b●b) = (c●c)


Sorry For Mistakes!!..
