PYTHAGOREAN RELATIONSHIP

1) The "PYTHAGOREAN RELATIONSHIP" is the relationship between the LENGTHS of a right triangle. To know that the right triangle has a correct sides, you need to see if the two legs are equal to the hypotenuse.

cheleseb pythagorous post

1, explain the Pythagoras method
A+B=C
that method is the way you find out if the triangle is a right triangle. you take the a + b-c and fill the numbers in.
if the to legs add up to the hypotenuse then you have a right triangle.
2. answer this missing side.
one leg equals = 12 which is A side
the other = 5
so we go c=a+b
c2=12+5
c2= (12x12) + (5x5)
c2= 144+25
c2=169( sqaure root it )
c=13
so the answer will be the c= 13 2


3.is the triangle a right triangle? prove it !!!
well one side equals 8 the other equals 6 so
a2+b2=c2
8+6=14
14 2=11 2
there for the triangle is not a right triangle.

Michael's Pythagorean Relatiohnship

1. Answer in a short paragraph and with diagrams



Answer:
c2 is equals to a2 + b2.



a2 + b2 = c2
52 + 122 = c2
25 cm2 + 144 cm2 = c2
169 cm2
13 cm2




a2 + b2 = c2
62 + 82 = 112
36 + 64 = 121
100 = 121
NOT A RIGHT TRIANGLE

Anmarie's pythagorean relationship post

The Pythagorean Relationship can be used to show if a triangle is a right triangle.
Left side:
6 squared+8 square= 10 squared
(6x6)+(8x8)=(10x10)
36+64=100















C squared= a squared+b squared
C squared= 12 squared+5 squared
C squared=(12x12)+(5x5)
C squared=144+100
C squared=244 squared
square root of "C" squared= square root of 244 is 15
C square= 15cm











8 squared+6 squared=11 squared
(8x8)+(6x6)=(11x11)
64+36=121
square root of "C"squared= square root of 121cm squared is 11
C=11cm
the triangle a right triangle.

Amiel's Pythagoras Post 4, 5, 10

4.what are the areas of the square?

e=30mm
e= 30²
e=30x30
e=900mm²

f=40mm
f=40²
f=40x40
f=1600mm²

g=50mm
g=50²
g=50x50
g=2500mm²

5. A right triangle has side length of 40mm, 75mm, and 85mm.
a) Sketch the right triangle and draw squares around each side of the triangle.

b) What are the areas of the three squares?

A=40mm B=75mm C=80mm
A=40² B=75² C=80²
A=40x40 B=75x75 C=80x80
A=1600mm B=5625 C=7225

c) Write an addition statement using the areas of these three squares.
A²+B²=C²

1600+5625=7225

10. A triangle has the side lengths of 120mm, 160mm, and 200mm. Is the triangle a right triangle? Explaing your reasoning.







a+b=c
120+160= 280
280≠200

It is not the a right triangle because the leg of the triangle did not equal the hypotenuse.

Ashlie's Pythagorean Relationship Post

The pythagorean relationship is used for solving problems for finding the hypotenuse with 2 given legs. Also to figure out if the triangle is a right triangle or not.

1. Find The Missing Side Length.

c2 = a2 + b2

c2 = 52 + 122

c2 = (5x5) + (12x12)

c = 25cm2 + 144cm2

c = 169cm2

square root of 169 = 13cm

c = 13cm

 2. Is This A Right Triangle? Show Your Work.

a2 + b2 = c2

62 + 82 = 112

(6x6) + (8x8) = (11x11)

36 + 64 = 121

  100 /= 121

Not a perfect square because the legs don't make/equal the hypotenuse.

mikyL's pathagorous scribe post

in this unti we have learned about the pythagours system. in this unit we have read worked and listened to mr.harbeck talk about what im gonna talk about.



first of all:



we learned about the system its self.



hypotenuse- the right triangles largest slide in between the legs. the hypotenuse can be calculated many different ways as i will explain in ferther explanations.
yellow: 7cm
blue 4cm
purple:?


pathegrous- if you look to the left this is a pathagorous question.
to calculate it you need to know how much the sqaures are each worth. so we know that yellow is worth 7cm and blue is worth 4cm. so nopw we know that A(sq.) + B(sq.) = C(sq.)
so to calculate that you do A+B+C
4+7=11cm (sq.)
now not always you will have a triangle that is a right triangle. if it is not a right triangle you must state that it isnt and say why. for example if the triangle does not have a little square in the middle of the legs, then it may not add up equal and it will NOT be a right triangle. :)
i hope you like my pathagourus post. I DONT HAVE ALOT OF INFORMATION BUT IF YOU HAVE ANY COMMENTS THEN POST THEM BELLOW AND I WILL TRY AND ANSWER THEM TO MY BEST ABILITIES :) THANKS!

Pythagoras post

3. Determine the length of each hypotenuse.

a)
c squared = a squared + b squared
c squared = 12 squared + 16 squared
c squared = (12 x 12) + (16 x 16)
c squared = 144 + 256
c squared = 400 cm squared
Then squared root "c" squared and square root 400 cm squared
c = 20 cm


b)
r squared = p squared + q squared
r squared = 16 squared + 30 squared
r squared = (16 x 16) + (30 x 30)
r squared = 256 + 900
r squared = 1156 m squared
Then square root "r" squared and then squared root 1156 m squared
r = 34 m

4. What is the length of each hypotenuse? Give your answer to the nearest tenth of a centimeter.
a)
z squared = x squared + y squared
z squared = 6 squared + 7 squared
z squared = (6 x 6) + (7 x 7)
z squared = 36 + 49
z squared = 85 cm squared
Then square root "z" squared and then square root 85 cm squared.
z = 9.21 cm

b)
d squared = b squared + c squared
d squared = 8 squared + 11 squared
d squared = (8 x 8) + (11 x 11)
d squared = 64 + 121
d squared = 185 cm squared
Then square root "d" squared and then square root 185 cm squared
d = 13.6 cm

5.
a) What is the area of each square attached?

a squared = 6 squared
a squared = 6 x 6
a squared = 36 cm squared

b squared = 8 squared
b squared = 8 x 8
b squared = 64 cm squared

b) c squared = a squared + b squared
c squared = 36 + 64
c squared = 100 cm squared

c) square root "c" squared and then square root 100 cm squared
c = 10 cm

Ayra's Pythagorean Post

1. Answer in a short paragraph and with diagrams 
The relationship between the lengths of the side of the right triangle. The sum of the areas of the squares attached to the legs of a right triangle equals the area of a square attached to the hypotenuse. 








the Pythagorean relationship can be used to show if a triangle is a right triangle.
Left side:
7 squared+6 square= 13 squared
(7x7)+(6x6)=(13x13)
49+36=85
square root of "C" squared= square root of 100cm squared is 10
C=10cmthe sum of the areas of the two smaller squares is 100cm squared.
the triangle is a right triangle. 


2. Solve for the missing side length 
 
a squared+b squared= c squared
8 squared+6 squared=11 squared
(8x8)+(6x6)=(11x11)
64+36=121
square root of "C"squared= square root of 121cm squared is 11
C=11cm
the triangle a right triangle. 


3. Is this a right triangle? Prove it!!!










a squared + b squared = c squared 
8 squared + 6 squared = 11 squared 
(8x8) + (6x6) = (11x11)
64 + 36 = 121
It's not a right triangle because it's not equal. The legs aren't equal to the hypotenuse.

Carlo's Pythagorean Relationship

1. The relationship between the lengths of the side of a right triangle. The sum of the areas of the squares attached to the legs of a right triangle equals the area of the square attached to the hypotenuse.

2. Solve for the missing side length.

3.Is this a right triangle??

Not A perfect Triangle.

anton816

"A²+B²" stands for the two legs."C²" stands for the hypotenuse.If the two legs and the hypotenuse are equal the triangle is right.

Ex.

Side length Area Formula

A 6 36 A²+B²=C²
B 8 64 6²+8²=10²
C 10 100 36+64=100

100=100(right triangle)

A²+B²=C²

12cm+5cm=C²

144+25cm=C²

C²=169cm²

C=13cm

A²+B²=C²

8+6=11

64²+36²=121²

100cm²=121cm²

(This is NOT a Right Triangle because the legs and the hypotenuse are not equal)

the triangle is a right triangle.

"A" squared + "B" squared = "C" squared means
A number times it self so 2 squared means 2x2 and 6 squared is 6x6









8 squared + 6 squared = 11 squared
A squared + B squared = c squared
(8x8) + (6x6) = (11x11)
64 + 36 = 121
the total is 121 cm
