The Pythagorean Triple A Pythagorean triple is when you add 2 perfect squares together to get another perfect square. The formula for this is a² + b² = c².

To find out the squares in between you may also use a
Perfect Square Chart :

A Pythagorean Triple is made up of perfect squares, another Pythagorean triple besides 3,4,and 5 is 6,8, and 10. Six squared is 36 Plus 64 from 8 squared equals 100 which is the square root of 10.

My own Problem: TIMMY AND THE RED BALL

Part 1:
What is a Pythagorean Triple?
-A Pythagorean Triple is 2 square numbers that when added together, equal another square number. The equation for one is:
a
² + b² = c²

There are many Pythagorean Triples, but often are confusing to find because when you look at a number squared, like 5
², you often ignore or don't see the little ² and end up multiplying by 2 instead of multiplying by 5 again, which is what you should have done. This mistake makes a big difference. 10 is a smaller than 25, and everybody knows that specific math questions have to have an exact answer. A number squared simply means that number times itself. The opposite of squaring is square rooting, which is finding what number times itself equals the larger number.

Anyway, here is my perfect square chart. The highlighted numbers or the ones that are the same color is 1 Pythagorean Triple.

Part 2:

Part 3:

Word Problems:

When reading math related word problems, underline important parts and circle the key numbers. Cross out unnecessary or unimportant information, if there is some:

A pictorial version of this problem would be:

The sides are 90 units because, since the measurements of the sides weren't given, you have to go to common sense for help. A square is 360 degrees, meaning it has 4 right angles (90 x 4 = 360). A triangle is half of a square, so it has 180 degrees (90 x 2 = 180) in angle. But we aren't finding the angle of the sides, but the length. So the degrees sign (°) is replaced with units (or u) in place of a measurement.
The new picture of the problem looks like this:

Now we can simply do the equation a² + b² = c² to solve this:
a² + b² = c²
90²+ 90²= c²
8100+8100=c²
16 200=c²

√16 200 = √c²

127.27= c

So the missing hypotenuse is 127.27 units in length. You have to throw the ball 127.27 units from first base to third base to get throw the runner out.

Part 4:

You are racing down the street on your new 10 speed bike. You see a ramp that 2 of your friend are hauling, and you must jump it to prove you aren't a noob. But your stupid friends are hauling it way further than they are supposed to, 3 meters left of you instead of being straight ahead of you. You are 10 meters away now and must swerve to jump the ramp and end up having to jump at an angle. How many meters do you have to swerve to get to that ramp?

Now, with the key parts highlighted:

What we know:
a = 3 meters
b = 10 meters
c = ?

Here's a little doodle I made on how the problem would look.

Now that we have the numbers, we just do the equations and solve it.
a² + b
² = c²
3
² + 10² = c²
9
+ 100 = c²
109 = c
²

√109 = √c²
10 9/21 = c

10 9/11 = 10.42
c = 10.42
c²= 109

So, after solving what the missing side was, you now know that you must swerve 10.42 (closest to 10) meters to the left to jump the ramp. Once you do that, and don't break your neighbors car from jumping onto it, you can retire from your career of dare-deviling and get a nice job as a professional lawn mower.

Today in class we reviewed for our test this upcoming Thursday with 3 questions that Mr. Jerema gave us to do. The questions we did are shown in the pictures below.

Question 1

Question 2

Question 3

Pythagorean Theorem: Problem A
You are locked out of your house and the only open window is on the second floor, 25 feet above the ground. You need to borrow a ladder from one of your neighbors. There's a bush along the edge of the house, so you'll have to place the ladder 10 feet from the house. What length of ladder do you need to reach the window?
In this picture I made of the problem, the bushes were removed, but we still have to solve the problem.
To find the missing side, you have to run through the Pythagorean Theorem and find out what the missing side is.
a = 25 feet
b = 10 feet
c = ?
a² + b² = c²
25² + 10² = c²
625 + 100 = c²
725 = c²
square root
of 725 = c²
Now we make the fractional then decimal form of the square root of 725.
Since 26 is 1 unit larger than 25, we have to square the number 26 and subtract that number from 725 (725 - 676).
27 x 27 = 729 - we can't use this because its larger than 725
26 x 26 = 676
So, back to the subtraction:
725 - 676 = 49
49 becomes the numerator of the fraction after 26.
To find the denominator, you have to add 26 with the number after it, which is 27
26 + 27 = 53.
The answer to 725 squared = 26 49/53
But we aren't done yet, we have to make it into a decimal form. *opens calculator*
26 49/53 = 26.924
26.924 = C
26.924² = c²
So the missing side length of the picture above is 26.924.

Another way we could have found the fraction after 26 is doing the "mullet" strategy.

D = Denominator of fraction after 26

### Jonah's Scribe Post

Today in class we were told to take out a piece of paper and copy what was on the board. It was a picture of a right angle triangle. We were supposed to find out the missing side we had 6 minutes to do it. The triangle looked like this:
We didn't know until the middle of working that what we were doing was a test. When we were done we had to mark it. To get full marks we had to have shown all of our work which included all of these things:

After we did the test we did something else in our blue Pythagoras booklet. We watched a scene of the movie Flushed Away and Mr. Jerema made it into a word problem. He drew a picture of a frog and we had to find out what was the missing side. But instead of looking at a picture we had a word problem. It looked like this:

The word problem was:
Le Frog (the name of the frog) stands 1.5 m from the wall where a fly is 2 m high. If the frogs tongue comes out of his mouth 70 cm from the ground, how far does his tongue have to stretch to trap and eat the fly? We used the pythagorean theorem to solve the missing side, since the side that was missing was the hypotenuse.
a + b = c
1.3 (x 1.3) + 1.5 (x 1.5) = c
1.69 + 2.25 = c
c 2 = 3.94
c = 1.98

This is what we did in class. Sorry if I missed something. But I don't think I did. So...don't forget to do your Pythagoras Growing Post if you haven't started it yet.

### Kenneth's Pythagoras Growing Post

Describe what a Pythagorean Triple is and use your perfect square chart from 1 squared to 10 squared to find another one other than 3,4,5. (Note: You need a picture, not simply text.)
The Pythagorean Triple is a triangle that has 3 sides to it with a right angle. The small sides of the triangle are labeled (a and b) legs. The longer side is (c) or the hypotenuse, when you add the squared legs together it will add up to the hypotenuse. In other words as + bs = cs, when you put numbers to replace the letters you will get 3s + 4s = 5s = 9 + 15 = 25. ( the s stands for squared )

### Jonah's Pythagoras Growing Post

Part 1:
Describe what a Pythagorean Triple is and use your perfect square chart from 1 squared to 10 squared to find another one other than 3,4,5.
This a PERFECT SQUARE CHART it will help you to find a Pythagorean Triple:
In a right angle triangle, there are 3 sides. They are A and B (which are legs) and C (which is a hypotenuse). The Pythagorean Theorem states that a + b = c. ( Leg + Leg =Hypotenuse).
Part 2:
Using embeddable web 2.0, describe how to find the missing side of a Right Triangle using the Pythagorean Theorem, show how to solve both for a missing leg and the hypotenuse.

Part 3:
Explain how to solve a Pythagoras word problem. Use one of the examples we covered in class (Worksheet A, B, LeFrog or Bonus Problem).
First we circle all the numbers in the problem and underline all the important facts. It help us since if we put it all together then it will make more sense, by just picking out what is important. Then we draw a diagram of the question with all the information we gathered in the right places.
Once we have drawn the diagram we can answer the question.

Part 4:
Now that you have seen many Pythagorean problems, create your own word problem.

### Megan's Pythagoras Growing Post

"Describe what a pythagorean triple is and use your perfect square chart from 1 squared to 10 squared to find another one other than 3,4,5."

The pythagorean triple shows us that the size of the legs (a & b) of a right angle triangle makes the square of the hypotenuse (c). The hyopotenuse or 'C' is found on the opposite side of the right angle and is the longest side of the triangle. (Which should be easy to spot.)
So basically, this means that the triple/formula for finding 'C' is A2(squared) + B2 = C2. The numbers A and B should be smaller then the number for C. Which means that C should have the largest number. Any numbers can be put for A, B and C as long as the equation works.

This is what a perfect square chart looks like:

( The black 2's stands for squared )

12 = 1
22 = 4
32 = 9
42 = 16
52 = 25
62 = 36
72 = 49
82 = 64
92 = 81
102 = 100

another example for pythagorean triple only reaching up to 10 is 6,8,10.
