# Are all right triangles Pythagorean triples?

The name is derived from the Pythagorean theorem, stating that every right triangle has side lengths satisfying the formula a2 + b2 = c2; thus, Pythagorean triples describe the three integer side lengths of a right triangle. However, right triangles with non-integer sides do not form Pythagorean triples.

Considering this, which is the hypotenuse?

In geometry, a hypotenuse (rarely: hypothenuse) is the longest side of a right-angled triangle, the side opposite of the right angle. The length of the hypotenuse is the square root of 25, that is, 5.

What are the sides of a right triangle called?

The relation between the sides and angles of a right triangle is the basis for trigonometry. The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (or catheti, singular: cathetus).

What is the law of sines used for?

In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of a triangle (any shape) to the sines of its angles. It can also be used when two sides and one of the non-enclosed angles are known.

## How do you identify a Pythagorean triple?

Determine if the following lengths are Pythagorean Triples. Plug the given numbers into the Pythagorean Theorem. Yes, 7, 24, 25 is a Pythagorean Triple and sides of a right triangle. Plug the given numbers into the Pythagorean Theorem.

## How many Pythagorean triples are there under 100?

Of these, only 16 are primitive triplets with hypotenuse less than 100: (3, 4,5), (5, 12, 13), (8, 15, 17), (7, 24, 25), (20, 21, 29), (12, 35, 37), (9, 40, 41), (28, 45, 53), (11, 60, 61), (33, 56, 65), (16, 63, 65), (48, 55, 73), (36, 77, 85), (13, 84, 85), (39, 80, 89), and (65, 72, 97) (OEIS A046086, A046087, and

## Do Pythagorean triple have to be whole numbers?

See, Pythagorean triples are the integers that fit the formula for the Pythagorean Theorem. These are whole numbers that can’t be decimals. Because all Pythagorean triples solve the formula for the Pythagorean Theorem, you can take any Pythagorean triple and make a right triangle out of it.

## What are the two special right triangles?

A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°.

## How do you know if it is a right triangle?

Note that the Pythagorean Theorem only works with right triangles. You can use the Pythagorean Theorem to find the length of the hypotenuse of a right triangle if you know the length of the triangle’s other two sides, called the legs. Put another way, if you know the lengths of a and b, you can find c.

## What are two Pythagorean triples?

The square of the length of the hypotenuse of a right triangle is the sum of the squares of the lengths of the two sides. This is usually expressed as a2+b2 = c2. Integer triples which satisfy this equation are Pythagorean triples. The most well known examples are (3,4,5) and (5,12,13).

## What are the angles of a 3 4 5 triangle?

Because it is a right triangle one angle is obviously 90°. The other two are approximately 36.87° and 53.13°. An everyday example. The 3:4:5 triangle is useful when you want to determine if an angle is a right angle.

## What is a Pythagorean triplet?

“Pythagorean triples” are integer solutions to the Pythagorean Theorem, a2 + b2 = c2. I like “triplets,” but “triples” seems to be the favored term. For a right triangle, the c side is the hypotenuse, the side opposite the right angle.

## How many Pythagorean triples are there?

So we can make infinitely many triples just using the (3,4,5) triple. Euclid’s Proof that there are Infinitely Many Pythagorean Triples.

## What is the meaning of Pythagoras twin?

Twin Pythagorean Triple. A twin Pythagorean triple is a Pythagorean triple for which two values are consecutive integers. By definition, twin triplets are therefore primitive triples. Of the 16 primitive triples with hypotenuse less than 100, seven are twin triples.

## What is a primitive Pythagorean triple?

A Pythagorean triple is a set of three positive integers a, b, and c having the property that they can be respectively the two legs and the hypotenuse of a right triangle, thus satisfying the equation ; the triple is said to be primitive if and only if a, b, and c share no common divisor.

## What is a family of Pythagorean triple?

A family of right triangles is associated with each Pythagorean triple. For example, the 5 : 12 : 13 family consists of the 5-12-13 triangle and all other triangles of the same shape that you’d get by shrinking or blowing up the 5-12-13 triangle. Just multiply the length of each side by the same number.

## Who was Pythagoras?

Pythagoras, (born c. 570 bce, Samos, Ionia [Greece]—died c. 500–490 bce, Metapontum, Lucanium [Italy]), Greek philosopher, mathematician, and founder of the Pythagorean brotherhood that, although religious in nature, formulated principles that influenced the thought of Plato and Aristotle and contributed to the

## Why was Pythagoras killed?

He then went to Metapontum and starved himself to death. Some other accounts say that he was caught in a conflict between Agrigentum and the Syracusans and was killed by the Syracusans. Whatever was the cause of his death, according to most accounts he died in 495 BC. Pythagoras is believed to have died around 500 B.C.

## Why Pythagoras is famous?

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. He is credited with many contributions to mathematics although some of them may have actually been the work of his students.

## What did Pythagoras invent?

Pythagoras is credited with advances in mathematics and geometry, medicine and philosophy. The famous theorem, that the square of the hypotenuse of a right-angled triangle equals the sum of the squares of the other two sides, is named after him, but was already known to the Egyptians and Babylonians.

## When was Pythagoras death?

## Who was Pythagoras married to?

Some historians say that Pythagoras was married to a woman named Theano and had a daughter Damo, and a son named Telauges, who succeeded Pythagoras as a teacher and possibly taught Empedocles. Others say that Theano was one of his students, not his wife, and say that Pythagoras never married and had no children.

## Who was Pythagoras taught by?

Pythagoras was born in about 570 BC on the Greek island of Samos. His father was a merchant. Pythagoras was taught mathematics by Thales, who brought mathematics to the Greeks from Ancient Egypt, and by Anaximander, who was an earlier student of Thales.

## Are Hypotenuses only in right triangles?

The hypotenuse is the largest side in a right triangle and is always opposite the right angle. (Only right triangles have a hypotenuse). The other two sides of the triangle, AC and CB are referred to as the ‘legs’.
