Pythagorean theorem In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

- Let's try out the Pythagorean Theorem using this right triangle with sides of 5 and 12 cm, and a hypotenuse of 13 cm. We can verify that the Pythagorean Theorem is true by substituting in the values. The square root of 169 is 13, which is the measure of the hypotenuse in this triangle.

Pythagorean theorem Let ABC be a triangle with side lengths a, b, and c, with a2 + b2 = c2. Construct a second triangle with sides of length a and b containing a right angle. By the Pythagorean theorem, it follows that the hypotenuse of this triangle has length c = √a2 + b2, the same as the hypotenuse of the first triangle.

- According to the Pythagorean Theorem, the sum of the areas of the two red squares, squares A and B, is equal to the area of the blue square, square C. Thus, the Pythagorean Theorem stated algebraically is: for a right triangle with sides of lengths a, b, and c, where c is the length of the hypotenuse.

- Girls in Sparta had more freedom than girls in other Greek states. Spartan girls did athletics, gymnastics, dancing, music and singing. Pythagoras was a clever Greek who told us what we need to know about triangles in geometry. Pythagoras believed that beans had souls, and told his students never to eat beans.

- The Pythagorean theorem is used any time we have a right triangle, we know the length of two sides, and we want to find the third side. For example: I was in the furniture store the other day and saw a nice entertainment center on sale at a good price. The space for the TV set measured.

- Pythagorean Theorem Definition. In a right triangle the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse. then the hypotenuse is the side opposite to the right angle (AB) and the legs (BC and CA) are the sides containing the right angle. a2 + b2 = c2.

The Pythagorean Theorem A right triangle consists of two legs and a hypotenuse. The two legs meet at a 90° angle and the hypotenuse is the longest side of the right triangle and is the side opposite the right angle. The Pythagorean Theorem tells us that the relationship in every right triangle is: Example:

Pythagoreanism Two schools[edit] According to tradition, pythagoreanism developed at some point into two separate schools of thought, the mathēmatikoi (μαθηματικοί, Greek for Teachers) and the akousmatikoi (ἀκουσματικοί, Greek for listeners). Lastly, we have one admitted instance of a philosophic guild, that of the Pythagoreans.

- So the Pythagorean theorem states the area h^2 of the square drawn on the hypotenuse is equal to the area a^2 of the square drawn on side a plus the area b^2 of the square drawn on side b. We begin with a right triangle on which we have constructed squares on the two sides, one red and one blue.

- Determine which side(s) of the triangle you are solving for. The Pythagorean Theorem allows mathematicians to find the length of any one of a right triangle's sides as long as they know the lengths of the other two sides. Determine which of your sides has an unknown length-a, b, and/or c.

Pythagoras of Samos Pythagoras was the head of the society with an inner circle of followers known as mathematikoi. The mathematikoi lived permanently with the Society, had no personal possessions and were vegetarians. They were taught by Pythagoras himself and obeyed strict rules.

Surprising Uses of the Pythagorean Theorem But most of us think the formula only applies to triangles and geometry. Think again. The Pythagorean Theorem can be used with any shape and for any formula that squares a number. Read on to see how this 2500-year-old idea can help us understand computer science, physics, even the value of Web 2.0 social networks.

Geometry/Right Triangles and Pythagorean Theorem The side opposite of the right angle is called the hypotenuse. The sides adjacent to the right angle are the legs. When using the Pythagorean Theorem, the hypotenuse or its length is often labeled with a lower case c. The legs (or their lengths) are often labeled a and b.

Pythagorean Theorem Pythagorean Theorem. In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. Try this Drag the orange dots on each vertex of the right triangle below. The formula showing the calculation of the Pythagorean Theorem will change accordingly. Although Pythagoras' name is attached to this theorem, it was actually known centuries before his time by the Babylonians.

Thomas Bayes and Bayesâs Theorem It's simple. Just use Bayes' theorem. The probability she likes you is. [math]P(like|smile) = \frac{P(smile|like)P(like)}{P(smile)}[/math]. [math]P(like|smile)[/math] is what you want to know-the probability she likes you given the fact that she smiles at you.[math]P(smile|like)[/math] is the probability that she will smile given that she sees someone she likes. [math]P(like)[/math] is the probability that she likes a random person.or example, suppose she just smiles at everyone. Then intuition says that fact that she smiles at you doesn't mean anything one way or another. Indeed, [math]P(smile|like) = 1[/math] and [math]P(smile)=1[/math] , and we have.

Pythagoras Considered a mathematician, but foremost a philosopher, Pythagoras was a very important figure in mathematics, astronomy, musical theory, and in the world's history. However, little in the way of reliable record is known about his life and accomplishments.he Pythagorean (hypotenuse) theorem states that the square of the hypotenuse of a right-angle triangle (c) is equal to the sum of the squares of the other two sides (a and b), shown as c 2 = a 2 + b 2. The numbers 3, 4, and 5 are called Pythagorean numbers (5 2 = 3 2 + 4 2, or 25 = 9 + 16).

- The square root of twenty-five is five, therefore the third side of the triangle is 5 units long. This theorem is a notable contribution to mathematics for which Pythagoras is known. Pythagoras was born between the years of 585 to 569 B.C.E. in Samos, an Aegean island.He left Samos at the age of eighteen to study in Phoenicia, Egypt, and possibly Babylonia. He died around 500 B.C.E.he square root of twenty-five is five, therefore the third side of the triangle is 5 units long.

Unit Circle Pythagoras. Pythagoras' Theorem says that for a right angled triangle, the square of the long side equals the sum of the squares of the other two sides: x 2 + y 2 = 1 2. But 1 2 is just 1, so:x2 + y2 = 1 (the equation of the unit circle). Also, since x=cos and y=sin, we get: (cos(θ))2 + (sin(θ))2 = 1.ythagoras. Pythagoras' Theorem says that for a right angled triangle, the square of the long side equals the sum of the squares of the other two sides: x 2 + y 2 = 1 2. But 1 2 is just 1, so:

Pythagoras It is possible that Pythagoras had a variety of teachers as a boy and a young man. Some of these teachers were Greek and some might have been Egyptian or from the East. It is even said that he might have been taught ethics by a woman called Themistoclea, who was a priestess from the oracle at Delphi.
