What is Pythagoras' Theorem? (Something to do with maths I think)?

Answer 1

it is to do with triangles, to find the length of a side of a triangle when you have the other two sides. The general rule is a²+b²=c², a,b and c being the sides of the triangle.

Answer 2

In mathematics, the Pythagorean theorem or Pythagoras' theorem is a relation in Euclidean geometry among the three sides of a right triangle. The theorem is named after the Greek mathematician Pythagoras, who by tradition is credited with its discovery, although knowledge of the theorem almost certainly predates him. Pythagoras was noted for his obsession with ratios. He believed that ratios could be applied to all aspects of the world.


The Pythagorean theorem: The sum of the areas of the two squares on the legs (a and b) equals the area of the square on the hypotenuse (c).The theorem is as follows:

In any right triangle, the area of the square whose side is the hypotenuse (the side of a right triangle opposite the right angle) is equal to the sum of areas of the squares whose sides are the two legs (i.e. the two sides other than the hypotenuse).

Answer 3

Pythagoras theorem states that in a right angled triangle the square of
the hypotenuse is equal to the sum of the squares of the other two sides
of the triangle.Hence if ABC is a right triangle in which the side AC is hypotenuse then AC^2=AB^2+BC^2

Answer 4

If you have a 5" square a 4" square and a 3" square and you put them together so that they form a triangle with sides of 3 4,and 5 you can see that the 5" square is 25 sq.inches which is equal to the sum of the areas of the other two squares,16sq inches plus 9 sq inches. This geezer called Pythagoras first put his name to it about 2000 years ago, but it's reasonable to suppose that he was not the first to be aware of it.

Answer 5

It says that the length of the hypotenuse squared is equal the the sum of the squares of the other two sides. This applies only to right angled triangles (triangles with one 90 degree angle).

So if a triangle has a hypotenuse of x length and the other two sides are of lengths 3 and 4 you sum the squares of each of these (9 and 16) then this is the square of x. Find the square root of this and you have the length of the other side (in this case 5).

Answer 6

The Pythagoras theorem is a fundamental theorem in geomentry

what it says is that in an right-angled trinangle (a triangle in which one angle is 90 degrees)

the sum of the squares of the sides flanking the right angle( the 90degree one) ... is equal to the square of the side opposite the right angle..

Answer 7

Pythagoras' Theorem is the formula A2+B2=C2 used to find the right (longest side) of the triangle.

Answer 8

It's one of maths study learning subjects here at Malaysia.overall about Pythagoras theorem, it just explain and brief you something specialized about triangle polygon

Answer 9

Cosider a triangle which has one 90-degrees angle.
Then, Pythagorean theorem relates the longest side to the other tow legs in the following way:

(length of hypotenuse)^2 = (length of leg1)^2 + (length of leg2)^2

So, once you know two sides' lengths in a right triangle, you can know the length of the remaining side using the Pythagorean theorem.

Answer 10

pythagoras's theorem applies to right angle trianlges and goes:
the square of the hypotenuse is equal to the sum of the squares of the two remaining sides.

hypotenuse^2 = opposite^2 + adjacent^2

where ^ means to 'the power' and ^2 means 'to the power 2' or 'sqaured' and the hypotenus is the longest side.

Answer 11

A^2 + B^2 = C^2

this is the formula to find out a length of a right angle triangle, where you already have two lengths. C is the longest length.
