Which theorem states that the square of the hypotenuse equals the sum of the squares of the legs?

Which theorem states that the square of the hypotenuse equals the sum of the squares of the legs?

Pythagorean theorem
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, a2 + b2 = c2.

Who found the sum of the squares of the legs of right triangle square of the hypotenuse?

Pythagoras
Pythagoras and his colleagues are credited with many contributions to mathematics. The following is an investigation of how the Pythagorean theorem has been proved over the years. The theorem states that: “The square on the hypotenuse of a right triangle is equal to the sum of the squares on the two legs” (Eves 80-81).

What does the Pythagorean theorem say about the areas of squares?

Pythagorean Theorem. The Pythagorean theorem states that in any right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the legs of the right triangle.

What does the converse Pythagorean theorem state?

The converse of the Pythagorean Theorem is: If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.

Where was the Pythagorean Theorem discovered?

The Pythagorean theorem was first known in ancient Babylon and Egypt (beginning about 1900 B.C.). The relationship was shown on a 4000 year old Babylonian tablet now known as Plimpton 322. However, the relationship was not widely publicized until Pythagoras stated it explicitly.

Who proved Pythagorean Theorem?

Euclid was the first to mention and prove Book I, Proposition 47, also known as I 47 or Euclid I 47. This is probably the most famous of all the proofs of the Pythagorean proposition.

Where was the Pythagorean theorem discovered?

What does the Pythagorean theorem find?

The Pythagorean Theorem states that the sum of the squared sides of a right triangle equals the length of the hypotenuse squared. If you know the length of any 2 sides of a right triangle you can use the Pythagorean equation formula to find the length of the third side.

What is Pythagoras theorem Class 10?

Pythagoras theorem states that “ In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides”. The sides of the right-angled triangle are called base, perpendicular and hypotenuse .

Who discovered Pythagoras theorem in India?

Baudhayana
Baudhayana (800 BC – 740 BC) is said to be the original Mathematician behind the Pythagoras theorem. Pythagoras theorem was indeed known much before Pythagoras, and it was Indians who discovered it at least 1000 years before Pythagoras was born! The credit for authoring the earliest Sulba Sutras goes to him.

Where is the Pythagorean theorem used?

Given two straight lines, the Pythagorean Theorem allows you to calculate the length of the diagonal connecting them. This application is frequently used in architecture, woodworking, or other physical construction projects. For instance, say you are building a sloped roof.

What is the Pythagorean theorem?

The Pythagorean theorem states that if a triangle has one right angle, then the square of the longest side, called the hypotenuse, is equal to the sum of the squares of the lengths of the two shorter sides, called the legs.

What is the hypotenuse of a right triangle?

The hypotenuse is the side of the triangle opposite the right angle. For right triangles only, enter any two values to find the third. See the solution with steps using the Pythagorean Theorem formula. This calculator also finds the area A of the right triangle with sides a and b.

How to prove the converse of Pythagoras theorem?

In a triangle, if the square of one side is equal to the sum of the squares of the other two sides, then the angle opposite the first side is a right angle. The converse of Pythagoras Theorem is proved.

How do you find the area of a square with hypotenuse?

So for a square with a side equal to a, the area is given by: So the Pythagorean theorem states the area h^2 of the square drawn on the hypotenuse is equal to the area a^2 of the square drawn on side a plus the area b^2 of the square drawn on side b . Here’s an interactive JavaScript program that let’s you see that this area relationship is true:
