### Pythagoras theorem history

1. 1. WELCOME TO MATHS WITH PROFESSORPHYTHAGOREAN THEOREM AND ITS ORIGIONS
2. 2. HISTORY OF PYTHAGORA S Birthplace of Pythagoras
3. 3. The Pythagorean OrderO Students at the Pythagorean School had to live by strict rules since they all strove to create pure minds and bodies.O They all thought that the mind could be purified through studying Geometry, mathematics, music, and astronomy.
4. 4. The Pythagorean OrderO Women were allowed to join the Order, but they were kept separated from the rest of the Order.
5. 5. Pythagorean Theorem What does the formula mean? O a² + b² = c² means that in a right the sum of the squares of the lengths of two legs equals the square of the length of the hypotenuse. c aFor a more in-depth look at how thisformula was derived, check out thissite:http://forum.swartmore.edu/~sarah/hamilton/ham.rttriangles.tml b
6. 6. There are Many Types of Triangles: Can you name them? Click on the names for the answers.Scalene Isosceles Equilateral Acute Obtuse Equiangular Triangle Right Triangle
7. 7. Important ContributionsO Pythagoras found mathematical relationships as the essence of all things.O He believed that the earth was spherical and that the sun, moon, and planets have movements of their own. This contributed to the discovery that the earth revolved around the sun.O He’s credited with developing the Pythagorean Theorem which is a formula that is used to determine the lengths of the sides of right triangles.O His discoveries laid the foundation for all subsequent developments in Geometry.
8. 8. WHAT IS A RIGT TRIANGLE ? O The Pythagorean Theorem applies only to right triangles. O A right triangle is a triangle that has a 90 degree right angle. It has two legs and a hypotenuse.a c O The hypotenuse is the side opposite the right angle and is b always the longest. O The variables a + b are used for the legs and c is the variable for the hypotenuse.
9. 9. Let’s See How it Works! Find the HypotenuseQuestion: If a = 3 and b = 4, then what does c equal? a² + b² = c² (3)2 + (4)2 = c² (3x3) + (4x4) = c² 9 + 16 = c² 25 = c2 a 25 = c² 5 = c b
10. 10. How to Find a Leg If a = 5 and c = 13, then what does b equal?O a² + b² = c² 52 + b² = 13² (5x5) + b² = (13x13) c 25 + b² = 169 a 25 + b² - 25 = 169 - 25 b² = 144 b² = 144 b b = 12
