The Pythagorean Theorem formula and daily uses


The Pythagorean Theorem formula is: a2+b2=c2. Which means that to find c we need to find the square root of a and b (the short legs of the right triangle), later add both square roots; and later find the square root of the sum.

For example: lets say that one short leg of a right triangle is 15cm (a) long and the other short leg is 20cm(b) long.
1.The first step to use it would be to find a and b´s square root which would equal: For A: 225, and for B: 400.
2.Later we would add both square roots: 400+225
3.We find the sum of the square roots: 625
4.We find the square root of the sum; which in this case would be 25.
5. At last we label the lenght of c with the correct unit, in this case the answer would be: that the lenght of c on on this right triangle would be 25cm.


Although this theorem may at first sound pretty boring, we actually use it every day.
Some of its daily uses are for example : finding the height of a building or the measurment of a TV.

As you may see, not only is the Pythagorean Theorem very interesting and fun; but it is very efficent on a daily basis.
