## What theorem is applied in number 12?

A 12-YEAR-OLD EINSTEIN ‘PROVES’ THE PYTHAGOREAN THEOREM Albert Einstein, age 12.

## Who invented rectangle?

it was the Egyptians and Mesopotamians although the Greeks made geometry books that were from the Egyptians.

**What is Pythagoras theorem class 7th?**

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 this triangle have been named Perpendicular, Base and Hypotenuse.

**What are theorems Byjus?**

A theorem is a statement to be proved. either on the basis of axioms or on the basis of previous proved statements. Example: Let a, b, c be the side lengths of a right angled triangle.

### What is Pythagoras’ theorem?

The Pythagoras Theorem states that in a right-angled triangle the sum of the square of the base and square of the perpendicular is equal to the square of the hypotenuse. If a triangle is right-angled (90 degrees), the square of the hypotenuse equals the sum of the squares of the other two sides, according to Pythagoras’ theorem.

### How do you prove the converse of Pythagoras theorem?

Converse of Pythagoras Theorem and its Proof 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. Given: In Δ X Y Z, X Y 2 + Y Z 2 = X Z 2 ∠ XYZ = 90 ∘

**What is the base of the Pythagorean theorem?**

Look at the triangle ABC below, where BC 2 = AB 2 + AC 2 . The base is AB, the altitude (height) is AC, and the hypotenuse is BC. The basic terms used in the Pythagoras Theorem are base, perpendicular (altitude), and hypotenuse.

**Which is the longest side of the Pythagoras theorem?**

According to the definition, the Pythagoras Theorem formula is given as: c 2 = a 2 + b 2. The side opposite to the right angle (90°) is the longest side (known as Hypotenuse) because the side opposite to the greatest angle is the longest.
