In Maths our class have been looking and working in the formula called Pythagoras Theorem. This formula is used when a triangle has a right angle triangle or sometimes called 90°. This formula is used to find the Hypotenuse, the hypotenuse is the longer side of the right triangle and the opposite side of the right triangle. In Pythagoras Theorem the sides are labelled by letters like (a,b and c) or anything but in algebra letters are numbers.
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.
