The Pythagorean Theorem is believed to have been was discovered on a Babylonian tablet circa 1900-1600 B.C.

The Pythagorean Theorem relates to the three sides of a right triangle . It states that c2=a2+b2, C is the side that is opposite the right angle which is referred to as the hypotenuse. A and b are the sides that are adjacent to the right angle.

The theorem simply stated is: the sum of the areas of two small squares equals the area of the large one.

You will find that the Pythagorean Theorem is used on any formula that will square a number. It's used to determine the shortest path when crossing through a park or recreation center or field. The theorem can be used by painters or construction workers, think about the angle of the ladder against a tall building for instance. There are many word problems in the classic math textbooks that require the use of the Pythagorean Theorem.

## History Behind Pythagorean's Theorem

Wapcaplet/Wikimedia Commons/CC BY 3.0

Hippasus of Metapontum was born in the 5th Century BC. It is believed that he proved the existence of irrational numbers at a time when the Pythagorean belief was that whole numbers and their ratios could describe anything that was geometric. Not only that, they didn't believe there was a need for any other numbers .

The Pythagoreans were a strict society and all discoveries that happened had to be directly credited to them, not the individual responsible for the discovery. The Pythagoreans were very secretive and did not want their discoveries to 'get out' so to speak. They considered whole numbers to be their rulers and that all quantities could be explained by whole numbers and their ratios. An event would happen that would change the very core of their beliefs. Along came Pythagorean Hippasus who discovered that the diagonal of a square whose side was one unit could not be expressed as a whole number or a ratio.

## What Is the Hypotenuse?

Jae Young Ju/Getty Images

Simply put, the hypotenuse of a right triangle is the side opposite the right angle. It is sometimes referred to by students as the long side of the triangle. The other two sides are referred to as the legs of the triangle. The theorem states that the square of the hypotenuse is the sum of the squares of the legs.

The hypotenuse is the side of the triangle where C is. Always understand that the Pythagorean Theorem relates the areas of squares on the sides of the right triangle

## Activity: A Pythagorean Puzzle

Lesson handouts, media locked, additional media.

## Our Teaching Philosophy:

Experience first, formalize later (effl), experience first.

To prepare for today's lesson, print the Shape Materials file found under "Additional Media" so that each page of the document is in a different color, preferably on cardstock. Each group will need one set of papers. Students will also need scissors and perhaps rulers.

Each group member will start with one of the four papers and cut out the shape(s) according to the instructions, then pass the paper to their group member. Set a timer for students so this part does not take longer than 5-8 minutes.

Next, students will work in groups on questions 1-6 in the activity using the shapes they just cut out. The goal is for students to understand that when we square a side length, we're referring to the area of a literal square coming off that side. The sum of the two smaller squares will always equal the large square. Most students can state "a^2 + b^2 =c^2" even before Geometry class, but few of them know what this means visually.

In the debrief, focus on question 6, where we label the lengths using variable names and then reason through equivalent areas. This is a great tie in to important Algebra standards about squaring binomials and the distributive property! Once you've established that the two figures have the same overall area, remove one triangle from both configurations at the same time. Ask students: "Do they still have the same area? Why?" This not only reinforces ideas about equivalence, but also helps students think about proof! Continue with these two questions for all 4 triangles, removing one at time. This may seem tedious, but it is worth it for students to see that at the end a^2 +b^2 is equal to c^2!

In questions 7 and 8, students consider obtuse and acute triangles. Note that only the angle is changing, not the lengths of the two "legs". In the case of an acute triangle, there is not necessarily a "large square", but we use this language to refer to the square across from the original right angle. Use this Geogebra applet for students to visualize how the areas of the squares are changing.

## Formalize Later

While we do use the variables a, b, and c, remind students that these are arbitrary choices. "c" is not code for hypotenuse, and they must re-assess in every question which sides are the legs and which is the hypotenuse. On homework and assessment questions, we like to label the side lengths as d, o, and g or some other three letter word and have students write an equation relating the three sides. We know some teachers prefer leg^2 +leg^2=hyptoenuse^2 for the more generalized version of the Pythagorean theorem, but this language does not translate as well to the criteria for obtuse and acute triangles, where there are no legs or hypotenuse.

When you assess students on the Pythagorean theorem, make sure you write some questions that relate back to the geometric representation of the squares. Otherwise, students will resort back very quickly to mimicking the procedure for finding a missing side algebraically. Question 1 in the Check Your Understanding is one way you can do this.

Below is an outline for a proof of the Pythagorean theorem's converse. Complete the proof by filling in the reasons. Suppose you have some triangle ABC, where the lengths of the sides satisfy the relationship a 2 + b 2 = c 2. a. Construct a right triangle with legs a and b (so there is a right angle between the sides with lengths a and b).

Figure 3.5.1 3.5. 1: Triangle ABC has vertices A A, B B, and C C. The lengths of the sides are a a, b b, and c c. The three angles of a triangle are related in a special way. The sum of their measures is 180∘ 180 ∘. Note that we read m∠A m ∠ A as "the measure of angle A.". So in ABC A B C in Figure 3.5.1 3.5.

Today, it has many applications in different areas of study, from simple elementary and high school geometry to complex engineering and architecture calculations. Below, we take a closer look at the theorem and how you can master it through a worksheet. What Is a Pythagorean Theorem Worksheet?

The Pythagorean Theorem says that. a2 +b2 = c2. a 2 + b 2 = c 2. In this example, the legs are known. Substitute 4 for a and 3 for b (3 for a and 4 for b works equally well) into the Pythagorean equation. 42 +32 = c2 4 2 + 3 2 = c 2. 3. Solve the Equation. 42 +32 = c2 16 + 9 = c2 25 = c2 5 = c The Pythagorean equation.

The area of the base is 0.5 (2.5 x 6) = 7.5 square units. You don't need to know a to find this base area. To find the surface area you need to know the areas

The Converse of the Pythagorean Theorem. The Pythagorean Theorem states that for a right triangle the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. This theorem can be modeled by the equation \(c^2=a^2+b^2\) where '\(c\)' represents the length of the hypotenuse, 'a' represents the length of one leg and '\(b\)' represents ...
