PYTHAGOREAN THEOREM

The Pythagorean Theorem is Pythagoras' most famous mathematical contribution. According to legend, Pythagoras was so happy when he discovered the theorem that he offered a sacrifice of oxen. The later discovery that the square root of 2 is irrational and therefore, cannot be expressed as a ratio of two integers, greatly troubled Pythagoras and his followers. They were devout in their belief that any two lengths were integral multiples of some unit length. Many attempts were made to suppress the knowledge that the square root of 2 is irrational. It is even said that the man who divulged the secret was drowned at sea.

What is a Pythagorean Theorem?
The Pythagorean Theorem is the sum of the areas of the two squares on the legs (a and b) equals the area of the square on the hypotenuse (c).


The legs are the two sides that makes the right angle.
The hypotenuse is the longest side of a right triangle.
RAT stands for Right Angle Triangle.
Pythagoras is greek.


The Thereom is A squared plus B squared equals C squared.
I think Mr Harbeck taught us the Pythagorean Thereom because we might use this in real life like architecture, building houses and other buildings. You can also be a teacher.

Here are some of the work :




There are three important sides of a triangle.
A triangle is a geometric figure consisting of three points or vertices which are connected with straight line segments called sides. When one of the angles of a triangle is a right angle, we call that a right triangle, as shown in this figure:

What is a relationship?
the relationship between the three sides of a right triangle (that is, between a, b, and c in the previous figure), let's look at an example of a relationship. In this example we will be calculating the perimeter or distance around the following rectangle:The perimeter or which you can call "P", you need to add the lengths of the four sides or a + b + a + b. It can also be expressed like this (p = 2a + 2b).

MEASURES OF CENTRAL TENDENCY

Here is an example of a work that I did in class
for MCT.

What are the range of the times?
What are the mean and median times?
Identify any possible outliers. Should the outlier(s) be removed from the data set?
Explain why or why not.














The Outlier would be 40.4 because its the biggest number out of all the numbers.


PROBABILITY


Here is an example of a work that I did in class for probability.


Billy is planning her summer vacation.

-She can go to Regina, Calgary, or Vancouver
-She can travel by bus, train, or plane
-She can stay with a friend or in a hotel





<-- The 1/8 is suppose to be 1/18. My bad









EQUATIONS
