Pythagoras Theorem

Phythagoras theorem is a right angled triangle that has hypotenuse and it's always the side opposite the right angle. It is the longest side in a right triangle. It states  that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

Example:

Image result for example of hypotenuseExample:
1.) Draw a Diagram and put the labels ( Right Triangle )
2.) Put the label A=(number) ,B=(number) and C = Hypotenuse ( you can change the letters if you want ) Ex: A = 15 
                   B = 8
                   C = ? = Hypotenuse
3.) Write down what is given.  
4.) Show the Proof / Formula
Formula : A (2) + B (2) = C (2)
The square root needs to be at 2
(2) = x times x
Ex: A (2) + B (2) = C (2)
       15 (squared) + 8 (square) = C (2)
       15 x 15 + 8 x 8 = C (2)
       225 + 64 = c(2)
       C = 289 
       Then squared root the 289 to find the answer. You need a calculator to find the squared root answer. Squared root = 
        square root of 289 is 17
5.) Answer = Squared root ( √ )v
The formula for right triangle is A (2) squared + B (2) squared = C (2) squared
Example:  A + B = C ( All needs have (2) square root ) 

EX: 
What can we use for Pythagoras Theorem is ladders, ex: how high is the building and can the ladder reach the building ?

  1. Hi Ian . Your post is very claear and I like how you have included a photo of your work. Your post would benefit from includeding practical applications of where you can use Pythagoras theorum. One example is a 90 degree coner on a building, builders do this regulary
