i need help with pytagoras theorem?

the equation is :

a² + b² = c²

Where a and b are the two shorter legs of a right-triangle (order doesn't matter as order of addition doesn't matter) and c is the length of the hypotenuse, the longest side.

Note this only works with right triangles.

So an example is, if you know the lengths of the two shorter sides is 3 and 4, what's the length of the 3rd side given it's a right-triangle, we have:

a² + b² = c²
3² + 4² = c²
9 + 16 = c²
c² = 25
c = 5

The length of the other side has to be 5.

Hope that helps. Best answer if it does.

The theorem describes the relationship between the sides and the hypotenuse of a right triangle.

A^2 + B^2 = C^2

A and B are the lengths of the sides. C is the length of the hypotenuse. The website below has some examples of this type of problem.

http://www.mathscore.com/math/practice/Pythagorean%20Theorem/

Let 5 meters and 8 meters be the lengths of the sides.

5^2 + 8^2 = C^2
C = √(25 + 64) = √89
This is approximately 9.4 meters.

Let 40 meters be the length of the hypotenuse, and 20 meters be the length of one of the sides.

20^2 + B^2 = 40^2
B^2 = 40^2 – 20^2 = 1200
B = √1200
This is 34.6 meters.

You can find example of these problems at similar websites. If you have some specific questions, you can contact me at the following email address.

A week ago.

If you know two sides, you can find the third.
(leg₁)² + (leg₂)² = (hypotenuse)²

It is simply the relationship of the sides to the hypotenuse of any right triangle...

h^2=x^2+y^2
