# When should I use the Pythagorean Theorem?

The Pythagorean theorem is used any time we have a right triangle, we know the length of two sides, and we want to find the third side. For example: I was in the furniture store the other day and saw a nice entertainment center on sale at a good price. The space for the TV set measured 17″ x 21″.

There are many uses for the Pythagorean Theorem, that is the main reason why it is important. You can use the Pythagorean Theorem to find out if a triangle is an acute triangle, obtuse triangle or a right triangle. Another reason the Pythagorean Theorem is imported is it can help you find missing side lengths.

Beside above, who uses Pythagorean Theorem? Production Workers and the Pythagorean Theorem This field is very diverse, encompassing everything from machinists and welders to foundry workers. Even here the concept of the sum of the squares of the lengths of the two legs of a right triangle being equal to the square of the length of the hypotenuse can be useful.

Simply so, how do you do the Pythagorean Theorem?

Draw a right triangle and then read through the problems again to determine the length of the legs and the hypotenuse. Step 2: Use the Pythagorean Theorem (a2 + b2 = c2) to write an equation to be solved. Remember that a and b are the legs and c is the hypotenuse (the longest side or the side opposite the 90º angle).

How are triangles used in real life?

Triangles are used to make rafters in buildings and curved domes. Some bridges have triangular structures, and the Egyptians made triangular-shaped pyramids. The shapes help surveyors use triangulation to determine the distance of a specific point from two other points of a known distance apart.

### What is Pythagorean theorems used for?

The Pythagorean theorem is used any time we have a right triangle, we know the length of two sides, and we want to find the third side. For example: I was in the furniture store the other day and saw a nice entertainment center on sale at a good price. The space for the TV set measured 17″ x 21″.

### Who invented Pythagorean Theorem?

The Pythagorean Theorem was one of the earliest theorems known to ancient civilizations. This famous theorem is named for the Greek mathematician and philosopher, Pythagoras. Pythagoras founded the Pythagorean School of Mathematics in Cortona, a Greek seaport in Southern Italy.

Blaise Pascal

### What is Pythagorean model?

Pythagorean astronomical system. From Wikipedia, the free encyclopedia. An astronomical system positing that the Earth, Moon, Sun and planets revolve around an unseen “Central Fire” was developed in the 5th century BC and has been attributed to the Pythagorean philosopher Philolaus.

### What is the Pythagorean theorem in simple terms?

Definition of Pythagorean theorem. : a theorem in geometry: the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.

### When was Pythagorean theorem created?

Although the theorem has long been associated with Greek mathematician-philosopher Pythagoras (c. 570–500/490 bce), it is actually far older. Four Babylonian tablets from circa 1900–1600 bce indicate some knowledge of the theorem, or at least of special integers known as Pythagorean triples that satisfy it.

### How do you make a2 b2 c2?

a2 + 2ab + b2 = c2 + 2ab Each side of this equation represents the area of the large square. a2 + b2 = c2 Subtract 2ab from both sides. The last equation, a2 + b2 = c2, is called the Pythagorean Theorem. We say “The sum of the squares of the legs of a right triangle equals the square of its hypotenuse.”

### What is hypotenuse of a triangle?

A right triangle consists of two legs and a hypotenuse. The two legs meet at a 90° angle and the hypotenuse is the longest side of the right triangle and is the side opposite the right angle. The Pythagorean Theorem tells us that the relationship in every right triangle is: a2+b2=c2.

### What is the Pythagorean theorem proof?

The Pythagorean Theorem says that, in a right triangle, the square of a (a2) plus the square of b (b2) is equal to the square of c (c2): a2 + b2 = c2.

### How fo you find the area of a triangle?

To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

### Does Pythagorean theorem work on all triangles?

Pythagoras’ theorem states that for all right-angled triangles, ‘The square on the hypotenuse is equal to the sum of the squares on the other two sides’. Pythagoras’ theorem only works for right-angled triangles, so you can use it to test whether a triangle has a right angle or not.

### What is a theorem in geometry?

A postulate is a statement that is assumed true without proof. A theorem is a true statement that can be proven. Listed below are six postulates and the theorems that can be proven from these postulates. Postulate 1: A line contains at least two points.

### How do u find the distance between two points?

Steps Take the coordinates of two points you want to find the distance between. Call one point Point 1 (x1,y1) and make the other Point 2 (x2,y2). Know the distance formula. Find the horizontal and vertical distance between the points. Square both values. Add the squared values together. Take the square root of the equation.
