prensentasi mengenai pythagoras

  1. 1. By Muhammad Hasan Bassari (20)
  2. 2. A. In mathematics, the Pythagorean theorem or Pythagoras theorem is a statement about the sides of a right triangle.B. One of the angles of a right triangle is always equal to 90 degrees. This angle is the right angle The two sides next to the right angle are called the legs and the other side is called the hypotenuse. The hypotenuse is the side opposite to the right angle, and it is always the longest side.C. The Pythagorean theorem says that the area of a square on the hypotenuse is equal to the sum of the areas of the squares on the legs. In this picture, the area of the blue square added to the area of the red square makes the area of the purple square. It was named after the greek MATHEMATICIANS PHYTAGORAS:D. If the lengths of the legs are a and b, and the length of the hypotenuse is c, then, .E. There are many different proofs of this theorem. They fall into four categories:F. Those based on linear relations: the algebraic proofs.G. Those based upon comparison of areas: the geometric proofs.H. Those based upon the vector operation.
  3. 3.  An algebraic proof proceeds by similarity. It is a property of Right triangles, such as the one shown in the above left figure, that the right triangle with sides , , and (small triangle in the left figure; reproduced in the right figure) is similar to the right triangle with sides , , and (large triangle in the left figure; reproduced in the middle figure). Letting in the above left figure then gives
  4. 4. Pythagoras of Samos (Ancient Greek: Πυθαγόρας ὁ Σάμιος [Πυθαγόρης in Ionian Greek] Pythagóras ho Sámios "Pythagoras the Samian", or simply Πυθαγόρας; b. about 570 – d. about 495 BC)was an Ionian Greekphilosopher, mathematician, and founder of the religious movement called Pythagoreanism. Most of the information about Pythagoras was written down centuries after he lived, so very little reliable information is known about him. He was born on the island of Samos, and might have travelled widely in his youth, visiting Egypt and other places seeking knowledge. Around 530 BC, he moved to Croton, a Greek colony in southern Italy, and there set up a religious sect. His followers pursued the religious rites andpractices developed by Pythagoras, and studied his philosophical theories. The society took an active role in the politics of Croton, but this eventually led to their downfall. The Pythagorean meeting-places were burned, and Pythagoras was forced to flee the city. He is said to have ended his days in Metapontum. Pythagoras made influential contributions to philosophy and religious teaching in the late 6th century BC. He is often revered as a great mathematician, mystic and scientist, but he is best known for thePythagorean theorem which bears his name. However, because legend and obfuscation cloud his work even more than that of the other pre-Socratic philosophers, one can give only a tentative account of his teachings, and some have questioned whether he contributed much to mathematics and natural philosophy. Many of the accomplishments credited to Pythagorasmay actually have been accomplishments of his colleagues and successors. Whether or not his disciples believed that everything was related to mathematics and that numbers were the ultimate reality is unknown. Itwas said that he was the first man to call himself a philosopher, or lover ofwisdom,and Pythagorean ideas exercised a marked influence on Plato, and through him, all of Western philosophy.
