To calculate a Pythagoras Theorem you have to read the problem and find out what they are looking for. Square root can be seen in the operation because it's a part of it.
What is the square root?
The square root is when the number has to be timed by itself like and the symbols of a square root can be √ N or N²
Here is the example to show how it works:
This is the diagram
First, you have to draw a diagram and put a label with a,b and c.
1. Next, write down what have you been given.
a = 5
b = 9
c =? Hyp
2. You write down the proof/theory formula.
"To calculate the distance of the c we can use the Pythagoras Theorem."
a² + b² = c²
3. After that, you write the numbers down and remember that the 2 beside the number given represent as a square root so it means it times by itself.
5² + 9² = c²
5x5 = 25
9x9= 81
4. Therefore you have to write down the two answers once you times the number by itself and then add answers together.
25 + 81 = 106
C² = 106
5. After you find out the answer when you add them together, you will now have to find the square root of the answer.
C² = 106
C² =√106
Ans = 10.29
One of the jobs that Pythagoras can be used is in a building they used the 3,4,5 triangle.
I did some research about Pythagoras Theorem like
"Where can I use Pythagoras Theorem in real life"?
I have found out that it can be used to calculate the steepness of slopes of hills or mountains. A surveyor looks through a telescope toward a measuring stick a fixed distance away, so that the telescope's line of sight and the measuring stick form a right angle.
Hey Jhermaine,
ReplyDeleteI really enjoyed reading your post. I found it easy to follow and feel that you have explained the topic well. My only confusion was around step 3... when you say square root is the ^2, I am pretty sure that square root is when you use division to find what number x itself makes the number, when you are using ^2 you say squared because it is the number x itself. Other than that well done.
