everyday applications of Pythagoras theorem?

Answer 1

Trigonometry, which is an entire branch of mathematics by itself, is derived from the Pythagoras theorem. It is because of the theorem that we know of Pythagorean triplets and their properties. Because of the theorem, we can draw a line having an irrational number as length. (Every hypotenuse of an isosceles right triangle is an example.)

The distance formula in Cartesian Coordinates is also derived from the theorem. This is very useful in maps drawn to scale to determine the length of routes and in general, the area occupied by a certain region or country.

Answer 2

to find distances like building heights
to find rope lengths
or the dimensions of a tv
or finding many other lengths


To be precise, you can measure right angles using this.

One example: You know that a telephone pole requires a cable to support it. You know that the pole is 4 meters high. The cable must be placed 3 meters from the base of the pole. Since the pole is perpendicular to the ground, you know you have a right triangle. The cable is the hypotenuse.

So, you can calculate c^2 = a^2 + b^2 = 3^2 + 4^2 = 25. So, c = 5. The cable must be 5 meters long.

It's a simple example, but it'll be useful. As you progress, you learn more about triangles, and how you can figure out lengths based on angles and what not.

Answer 3

Pythagoras theorem can be used to find the distance of any right angled figures on shapes. For example, the height of a biscuit when dipped in a cup of tea can be found out. It is that we are seeing the half side only .

Answer 4

Pythogorus theorem supports a manner of number-application by linking with 2D matrixes and hence it is very simple to grasp and apply! You will appreciate a number application is an everyday application!

Answer 5

Entire science of Trigonometry begins with three sides of a right angled triangle. Most waves in physics describe a sine theta curve.

Answer 6

Find the height of a tall object based on the shadow it casts, in comparison to an object of know height and the length of its shadow.
For example a flag pole; measure the shadow and a yard stick and measure its shadow, use a ratio to solve.
