What use, if any, is the theorem of pythagoras for today?

Answer 1

Non whatsoever. Just give a small child a Mechano set and let him build Telfords Bridge. Will work every time???

Answer 2

I am a man of 62 years old. I can not keep each and every value of trigonometry in my mind for ready reference. But still I remember the Pythagoras theorem. I am using in my every day research activities.A simple and easy to remember can be applied to solve several geometrical problems.I would not have designed several safety equipments if I do not know Pythagoras theorem and Newtons law of motions.

Answer 3

Lets not forget that the Pythagoras theorem is the building block of many mathematical theorems,it was used to create the sin rule,it is meant is a part of math(the laws of numbers and their odd relationship) and that on its own makes it important if it wasn't important Pythagoras himself would have never stolen the theorem.Using a ruler is easier by far and lets not lie,if you don't have one you can buy one.

Answer 4

I think brick layers use the 3 4 5 rule to get walls square (Pythagoras). If you measure 3 unit along one wall and 4 units along the other wall which should be a right angles to it. The measurement between those to points should be exactly 5 units.
Pythagoras in action.

Answer 5

If we settle on to instruct given triangle is ideal angled triangle , utilising pythagorus theorem in straightforward words. hyp^2= one section^2 + different section ^2 as an get mutually one section = 3 different section = 4 and it really is righgt angled triangle potential we detect hyp utilising pythagorus theorem hyp^2 = 3^2 + 4^2 hyp^2 = 25 hyp= 5

Answer 6

because if u don't have any ruler or anything you can use it to find out one side of a right angle triangle.
also could be use in real life.
example:
a ladder leaned against a wall
ladder= l
height of wall to the tip of the ladder=y
distance of ladder from the wall on the floor =x
x(squared)+y(squared)=l(squared)
finding the square root of l will give u the measurement for the ladder.

i think it's very useful
if the ladder was too tall and stuck and can't be measured diagonally.

don't u think sometimes it could help i mean they wouldn't teach it to us if it's not useful .............:) lol

Answer 7

Two of the more useful things I can think are these:
a) to find the height of an object at a known distance away.
b) in construction of large objects(house, etc.) to confirm an object is square.
c) and to show off to your friends for knowing what they may not.

Answer 8

To make flowerbeds in the middle of lawns with proper 90 degree corners?

Answer 9

It allows you to find the missing leg of a right triangle. It was the precusor to the Law of Sines (and the Law of Cosines), so engineers can use them to build force triangles and find necessary force values.

Answer 10

For finding the length of a hypotenuse in a right-angled triangle. And there are so many practical uses for that, I won't bother mentioning any!!
