They say that the hook stranded theorem is A2 B2 C2 so what is the hook 3 strand 4 string

Here comes the standard answer.

First of all, the 2 here is not the number in the hook three-strand five.

Here 2 is the meaning of squared.

That is, in a right triangle, a square + b square = c square.

A and B are both right-angled edges, and C is an hypotenuse.

The hook is the smallest integer right triangle.

That is, the two right-angled sides are 3 and 4, and the hypotenuse is 5

The square of 3 plus the square of 4 equals the square of 5.

Hooking 3 strands and 4 strings is a Chinese saying, see "Zhou Ji Shujing", ancient Chinese did not understand abc

The square of the hook + the square of the strand = the square of the string.

In a right-angled triangle, the shortest right-angled side is 3, the other right-angled side is 4, and the hypotenuse is 5; Or satisfy the shortest right-angled edge: the longest right-angled edge: the hypotenuse is 3:

The law of 4:5 is the Pythagorean theorem. The shortest right-angled edge is called a "hook"; The other right-angled side is the "strand"; The hypotenuse is a "chord".

It is a law of the relationship between the sides and lengths of a right triangle.

You're talking about the Pythagorean theorem.

The Pythagorean theorem is a fundamental elementary geometric theorem that states that the sum of the squares of two right-angled sides of a right-angled triangle is equal to the square of the hypotenuse. If the two right-angled sides of a right-angled triangle are a and b, and the hypotenuse is c, then a +b = c, (a, b, c) is called the Pythagorean array.

The Pythagorean theorem now has about 400 ways to prove it, making it one of the most provable theorems in mathematics. The Pythagorean theorem is one of the important mathematical theorems discovered and proven by mankind in the early days, one of the most important tools for solving geometric problems with algebraic ideas, and one of the links between numbers and shapes. "Pythagorean three, strand four, string five" is one of the most famous examples of the Pythagorean theorem.

The ancient Babylonians knew and applied the Pythagorean theorem as far back as about the third millennium BC, as well as many Pythagorean arrays. The Pythagorean theorem was also applied by the ancient Egyptians. In China, Shang Gao of the Shang Dynasty proposed a special case of the Pythagorean theorem of "Pythagorean three, four strings and five".

In the West, Pythagoras of ancient Greece was the first to propose and prove this theorem in the 6th century BC, who deductively proved that the square of the hypotenuse of a right triangle is equal to the sum of the squares of two right angles.

Using the Pythagorean theorem to find the length of a line segment This is the most basic application of the Pythagorean theorem, usually in a right triangle, the length of two sides is known, and the third side is found. For this kind of problem, it is relatively easy to directly substitute the formula for calculation. In many problems, this small step can arise to solve many big problems.

As one of the important mathematical theorems discovered and proven by mankind in the early days, the Pythagorean theorem has had a significant impact on the development of mathematics. The Pythagorean theorem enables people to solve geometric problems with algebraic ideas and concepts, which is the embodiment of the idea of "combination of numbers and shapes", and this ideological perspective is very important. At the same time, the discovery of the Pythagorean theorem has promoted mankind's deeper exploration of mathematical geometry. Through the Pythagorean theorem, we can deduce many other true propositions and theorems, which greatly facilitates our solution to geometric problems and makes a big step forward in the development of mathematics.

The Pythagorean theorem is a basic geometric theorem, in China, the formula and proof of the Pythagorean theorem are recorded in the Zhou Sutra, which is said to have been discovered by Shang Gao in the Shang Dynasty, so it is also called the Shang Gao theorem; Jiang Mingzu in the Three Kingdoms period made a detailed note on the Pythagorean theorem in the "Jiang Mingzu Sutra" and gave another proof. The sum of the squares of the two right-angled sides (i.e., "hooks", "strands") of a right triangle is equal to the square of the sides of the hypotenuse (i.e., "chord"). That is, if the two right-angled sides of a right-angled triangle are a and b, and the hypotenuse is c, then a +b = c.

The Pythagorean theorem has now found about 400 ways to prove it, making it one of the most provable theorems among mathematical theorems. Pythagorean array range a2 + b2 = positive integer array of c2 (a, b, c). (3,4,5) is the Pythagorean number.

In a right-angled triangle, the sum of the squares of the two right-angled sides is equal to the square of the hypotenuse.

The sum of the squares of the shorter sides of a right triangle is equal to the square of the longer side.

1. Using a hook with three strands, four strings and five as right angles is the stupidest method. To use a scale ruler, to use a straight line.

2. Find a branch and draw a semicircle and diameter on the ground, and the circumferential angle on the semicircle is a right angle.

3. Or, with a tree branch, draw an arc intersecting at two points, link the two intersection points to draw a straight line, and the angle formed by the line and the two center of the circle is also a right angle.

3 2+4 2=5 2 (here 2 squared).

The Pythagorean theorem can be represented by a triangle. In the above equation, 5 is the beveled edge, and 3 and 4 are the two right-angled edges, respectively.

The above relationship is a fact.

The two right-angled sides are 3,4 and the hypotenuse is 5. It's a special case of the Pythagorean theorem.

The two right-angled sides of a right-angled triangle are A, and the hypotenuse of B is C, then A squared plus B squared equals C squared.

This is the Pythagorean number in the Pythagorean theorem

The sum of the squares of the two right-angled sides of a right-angled triangle is equal to the square of the hypotenuse.

The square of a + the square of b = the square of c.

3 square + 4 square = 5 square.

is an expression of the Pythagorean theorem.

The length of the three sides of the triangle is a special case of the Pythagorean law.

That is, if one right side is 3 and the other is 4, then the hypotenuse is 5

Commonly known as "hook 3 strands 4 strings 5".

Pythagorean strands, four strings five, the smallest positive integer of the Pythagorean theorem, is a right-angled triangle.
