**A Practical Demonstration of the Pythagorean Theorem** by Mathematical Palette on Dec 19, 2012The Pythagorean Theorem is probably the most popular theorem in school mathematics. Surely, you have heard or read about it at least once from elementary school to high school. The Pythagorean Theorem states that given a right triangle with shorter s...

**Irrational Lengths and The Root Spiral** by Mathematical Palette on Dec 3, 2012When calculators were not yet invented, it was hard for mathematicians to approximate irrational numbers. The irrational numbers was the offshoot of the discovery that the side length of the diagonal of a square with side length 1 is irrational. But...

**The Pythagorean Theorem** by Proofs from The Book on Nov 10, 2012Introduction The Pythagorean Theorem is probably the most famous theorem in Geometry. Even elementary school pupils know it by heart. It states that the given a right triangle with legs , , and hypotenuse , . Although it is one of the easiest theo...

**Using Similarity to Prove the Pythagorean Theorem** by Mathematics and Multimedia on May 19, 2012The Pythagorean Theorem is one of the most interesting theorems for two reasons: First, it’s very elementary; even high school students know it by heart. Second, it has hundreds of proofs. The proof below uses triangle similarity. Pythagorean...

**Pythagorean Theorem Proof** by GeoGebra Applet Central on Feb 21, 2012Given congruent squares P and Q, each of which, containing four congruent right triangles. Move point A to change the size of the rectangle or point B to change the size of the squares.

**What is the role of visualization in mathematics?** by Mathematics for Teaching on Oct 3, 2011Mathematics for Teaching - This site is NOT about making mathematics easy because it isn't. It is about making it make sense because it does.TweetLike abstraction and generalization which I described in my earlier posts here and here,visualizati...

**Generating Pythagorean Triples from Square Numbers** by Mathematics and Multimedia on Jun 18, 2011A figurate number, is a number that can be represented by a regular geometrical arrangement of equally spaced points (or circles as shown below). If the arrangement forms a regular polygon, the number is called a polygonal number. Examples of a pol...

**Pythagorean theorem** by GeoGebra Applet Central on May 19, 2011Pythagorean Theorem: In any right triangle, the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares whose sides are the two legs. view the GeoGebra applet in a new tab. Sorry, the GeoGebra Applet cou...
