If a topic is in " " then you should paste the exact term into wikipedia as your search item

Topics:

1. Who is Euclid and what are three of his axioms. Euclid gives five postulates (axioms) in his first book of elements, which discribes Geometric terms.

2. What is the The "Pythagorean theorem"?

3. "Congruence (geometry)" Congruence (geometry). What are the three ways that triangles can be proven to be congruent (equal to one another) using sides and angles.

4. What is a "Wiki" and what is "collaborative writing"?

5. What is the "fibonacci sequence" and what are five examples of where it can be found in nature.

Have fun using this amazing web based resource. Use it to find out information on anything that we are learning in math class.

In math the pythagorean theorom, is a relation to the Eucli geometry between the 3 sides of a triangle. The theorem is named after Pythagoras. This theorom can be divided into 3 parts, the knowledge of Pythagorean triples, the relationship between the sides of a right triangle, and proofs of the theorem. The equation of the theorom is a^2 + b^2 = c^2.

Question:

4. What is a "Wiki" and what is "collaborative writing"?

Answer:

A "Wiki" is a type of website that gives anybody who visits the website the privelege to add or remove things. It also lets you edit anything. If you wish to make changes, it let's you edit things easily and rapidly. Sometimes, you might have the ability to change it without signing up.

Collaborative writing is what applies to some projects. they are projects that are acknowledged by various people. The projects are acknowledged by people working together than people who work individually.

fibonnaci sequence(or patttern):

a sequence in which specific, subsequent numbers are produced by adding the two previous "fibonaccci numbers". the pattern usually starts with 0 and 1. example: 0, 1, 1, 2, 3, 5, 8, 13, 21.

examples in nature:

1.arrangement of leaves in flowers

2.arrangement of pines on a pine cone

3.arrangement of seeds on a raspberry

4.arrangement of scales on a pineapple

5.arrangement of spirals in horns and shells

"Wiki" is a website that allows the people to very easy and very quikly, edit all contents.The term "Wiki" is also came from the native language of Hawaii, that means "quik" or "fast".

"Collaborative writing" refers to a projects written works that is created by multiple people togetlher or individualy.

2: What is the The "Pythagorean theorem"?

The converse of the Pythagorean theorem is also true. That is, a triangle in which the square of one side equals the sum of the squares of the other two sides is a right triangle.

4. What is a "Wiki" and what is "collaborative writing"?

A wiki is a web site that allows any person who goes to the web site to change, edit or add anything to it very fast and easily.Collaborative writing is when a bunch of people wright something together as a team instead of them writing something by themselves.

In geometry, a set is congruence when it has the same shape and size, but different position.

The shape could be rotated or flip.

Triangles are congruence if the size and angle are the same.

SAS(side-angle-side) is when 2 triangles have 2 same sides and 1 same angle.

SSS is when all sides are equal.

ASA is when 2 angles and 1 side are equal.

The fibonacci sequence is the sequence of numbers, 1, 1, 2, 3, 5, 8, 13,..., in which each successive number is equal to the sum of the two preceding numbers. The numbers first appear was under the name maatraameru. Five examples in nature are: the branching patterns of leaves in grasses and flowers, branching in bushes and trees, the arrangement of pines on a pine cone, seeds on a raspberry, and spiral patterns in horns and shells.

I did question number 5

5. What is the fibonacci sequence and what are five examples of where it can be found in nature

The fibonacci sequence starts with 0,1. To find the next fibonacci nimbers, you add the two previous numbers.

The pattern goes like this:

0,1,1,2,3,5,8,13,21,34,55,89,144

Fibonacci sequence found in nature:

I gave you seven, not five.

The fibonacci sequence is found in the branching pattern of leaves and trees, the pines of a pinecone, seeds on a raspberry, the patterns of horns and shell, the surface of a pineapple and the spiral of sunflower seeds.

Also, in the 12th century, it was a model of the growth of the population of rabbits.

4. What is a "Wiki" and what is "collaborative writing"?

*ANSWER

Wiki is a type of website that allows people to search, add, remove and edit without any registration.

Collaborative Writing are people working in a group, not just one person. The members in a group have their own roles and they all try to think and imagine the document that they are creating.

Hello Mr.Reece,

I will be answering question number 5.

First, the fibonacci sequence is a special sequence where you add the two numbers before to get the next number. You can create all sorts of cool patterns with it as well.

Secondly, you can find the fibonacci sequence in nature. The five places are branching patterns in flowers and grasses, branching in bushes and trees, the arrangment of pines on pinecones, the seeds on a raspberry and the spiral patterns in horns and shells. I wasn't sure if you would count the first two examples as being the same because they are alike so i gave an extra one just in case. Here it is, scales on the surface of a pineapple.

Question 5: A fibonacci sequence is a number pattern that is used with fibonacci numbers. To do the sequence you basically start with 0 and 1, and then you get the next number by adding the two previous fibonacci numbers. Five exmaples on where it can be found in nature are a pineapple, pine cones and spiral patterns on horns and seashells.

wiki: a website that anyone can edit quickly usuallly without registration

collaborative writing: projects that are done with multiple people together

Pythagorean theorem: a theory in which, in a right triangle, the area of the square whos side is the hypotenuse is equal to the sum of the other 2 squares on the triangle's other two sidez

By mark, at 4/27/2006 6:58 PM

Pythagonean Theorem is also known as Pythagoras's Theorem. It's a type of math where you have to find the lenths of a Right Triangle. The two lenths that are known can help you find the third lenth. When the lenths on the triangle are found you have solved it. It has to do with geomety.

"WIKI" is a website that can be updated by individuals. The individuals update this website by adding, or removing facts/information about a certain subject. WIKI is very useful for finding information on certain subjects. This website can also help you learn about interesting subjects.

"COLLABORATIVE WRITING" is a report of a certain subject that is created by combined individuals.

The three ways the triangle can be proven to be congruent using sides and angles.

1.) Two triangles are congruent if the three sides are equal.(SSS)

2.) Two triangles are congruent if thier corresponding sides and angle are equal. (SAS)

3.) Two triangles are congruent if a pair of corresponding angles and the included side are equal. (ASA)

By Camille T., at 4/29/2006 9:00 AM

Pythagorean theorem is a relation between three sides of a right triangle (90 degrees). It is also known as the knowledge of the relationship between the sides of a right angle. It is named after a Greek mathematician named Pythagoras.

4. What is a "Wiki" and what is "collaborative writing"?

Wiki:Wiki wikiis from the native language of Hawaii. The short form ofwiki wikiiswiki. It means "quick or "fast" in the Hawaiian dictionary and it is used as an adverb. In English dictionary it means "quickly" or "fast" and it is used as an adverb.Collaborative writing:Collaborative is an adjective. Collaborative writing means to work on a writing project, assignment, homework, etc. together instead of one person.

.An example of collaborative work is our BLOG at SPS (work together in a group not alone)********************************************************

Mr. Reece...SORRY if I posted it late...I totally forgot about it. *SORRY*By Levi, at 4/29/2006 1:48 PM

Hi Mr. Reece, sorry if this is a little bit late because my computer wasn't working properly so we got fixed and it took a while. I hope you understand...

4) What is a "Wiki" and what is "collaborative writing"?

Wiki is a short form of wiki wiki(weekie, weekie). It is from a native language of Hawaii. It is commonly used as an adjective that means quick or fast. It is sometimees interpreted as the backronym for "What I Know Is" which describes the knowledge contribution, storage, and exchange function.Wiki (wee-kee) is a also a type of website. It allows you to add, remove or edit the content easily and very quickly.

The term collaborative writing refers to projects where written works. Which are made by multiple people together rather than only one person. A very good method of discussion and communication is essential, especially if disagreements arise. Projects are easier to do this way if the group has a goal in mind . This is similar to group writing,

Thanx
