# An analysis of pythagorean theorem

Which positive integers are not part of a Pythagorean triplet? All the triples listed have no common divisor unlike 6,8, They are called primitive Pythagorean triples.

Extend the Order of Operations to include positive integer exponents and square roots. Include arithmetic and geometric progressions, e. Apply the theorem to the solution of problems.

Given the formulas, determine the surface area and volume of rectangular prisms, cylinders, and spheres. Use technology as appropriate. Differentiate between continuous and discrete data and ways to represent them.

The focus on the week should be on the relationships: Students will review exponents, particularly squares. Students will also review and expand their understanding of square roots. Students will use a calculator to find square roots. Students will learn how to find the area of a rectangle.

Students will use grid paper to draw rectangles and find the area of those rectangles by counting the square units. Students will create different rectangles with the same area. Students will work in partners to explore the formula for the area of a square. Students will relate the concept of square units to the previous day's lesson.

Students will also learn how to use the area to find the length of a side of a rectangle. Students will explore the area of triangles. Students will complete a guided activity in which they will cut triangles from grid paper and try to find the area.

Students will learn and use the formula for area of a triangle and understand how it is derived from the formula for area of a rectangle. Students should also be introduced to the terms leg and hypotenuse for right triangles. Students will arrange the smaller shapes to fit into the larger shapes.

Students will use calculations and algebraic expressions to give the area of the larger shapes using the information provided on the smaller shapes. Additional exercises and activities on concepts will be provided for further study and remediation.

This website also includes the templates for the in-class activities. If possible, the exploratory week would work best in a classroom that has both tables and enough computers for each group so that stations could be set up with the different activities. The activities could be completed in any order although activities four and five make the proof quite obvious.

This does provide an excellent opportunity to differentiate instruction based on the previous week's activities and teacher knowledge of the students. Students will be using applets and visual proofs to derive the Pythagorean Theorem. Students will work in cooperative groups that will set their own pace through the activities.

The teacher should circulate and conference with groups to check progress and understanding. Once a group has derived the formula and completed the five main activities, they can move on to investigate additional visual proof applets.

At the end of the week, groups will present an explanation of a chosen proof. The teacher will guide students toward using appropriate terminology and algebraic notation to support the visuals.

After the presentations, each group member will turn in an independent explanation of the group's chosen proof that incorporates the changes and improvements discussed during class time. The teacher will review the terms leg and hypotenuse prior to this activity.

If necessary, groups may be directed to the review portion of the website. Students will follow the instructions for this applet. Students will be moving the vertices of a triangle to create different right triangles and recording the lengths of the legs and hypotenuse in a table possibly in a spreadsheet.

The instructions encourage students to look for whole number sides. Students are encouraged to find a relationship between the three sides.

The teacher should circulate to determine whether or not groups should move on or continue trying to determine the relationship. If students understand the theorem after this activity, the same applet can be used to determine if the theorem works for other triangles.Pythagorean Theorem: The principle, made famous by baseball analyst Bill James, that states that the record of a baseball team can be approximated by taking the square of team runs scored and dividing it by the square of team runs scored plus the square of team runs allowed.

Statistician Daryl Morey later extended this theorem to other sports including professional football. It is called "Pythagoras' Theorem" and can be written in one short equation: a 2 + b 2 = c 2.

Note: c is the longest side of the triangle; a and b are the other two sides ; Definition. The longest side of the triangle is called the "hypotenuse", so the formal definition is.

The Pythagorean Theorem states that a² + b² = c². This is used when we are given a triangle in which we only know the length of two of the three sides. C is the longest side . Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a 2 + b 2 = c 2.
