how do u use pythagorean theorem?

Question

a^2 + b^2 = c^2

Answer 1

Easy, if you know two sides of a right triangle you can find the third.

a is a right angle side, b is a right angle side, and c is the hypotenuse (sp??)

Answer 2

Hey! OK, this is really easy once you get the hang of it. "C" is always the hypotenuese, which is the longest side of the triangle.
"A" and "B" are the two other sides, which are called the legs. It doesn't matter which is "A" and which "B" as long as you have the longest side for "C". If you are trying to solve for "C", you square both legs, then add them, after that, you take the square root of that number and that is "C". Here is an example:
A= 3
B= 4
C= x
3^2+4^2=x^2
9+16=x^2
25=x^2
take the square root of 25
5=x
Now you can do that the other way 'round too, just move all the numbers to one side, leaving the variable, or the "x" on it's own. Then do the same thing. Just remember this equation only works with right triangles. Hope this helped!

Answer 3

In algebraic terms, a2 + b2 = c2 where c is the hypotenuse while a and b are the legs of the triangle.

lets say you have a triangle and one side is 4 ft and the other is 4 ft but the third side is unknown. first you do 4squared + 4squared = csquared.
16 + 16 = 32
so you do 32 = c2
you do the square root of 32 which is 5.65 or 5.6 and thats will be your answer

Answer 4

Knowing the length of two sides of a right triangle, you can calculate the third.
