## What is Ispythagoras theorem?

The Pythagoras theorem states that if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides. In the given triangle ABC, we have BC2 = AB2 + AC2​​. Here, ​​​​AB is the base, AC is the altitude or the height, and BC is the hypotenuse.

## What is the converse of Pythagoras?

The converse of the theorem says that if, a 2 = b 2 + c 2 then you have a right-angled triangle and furthermore, the right angle is directly opposite. (the hypotenuse). We can therefore use the converse to check whether a triangle is right-angled or not.

What is Gougu theorem?

The Gougu Theorem is that “in the right triangle, the sum of the squares of two right sides is equal to the square of the hypotenuse.” In other words, the three sides (a, b, c) of right-angled triangle satisfies the following equation: a2+b2=c2 Where a is called 勾/Gou, b is 股/Gu, and c is 弦/Xian.

How do you calculate C2?

The formula is A2 + B2 = C2, this is as simple as one leg of a triangle squared plus another leg of a triangle squared equals the hypotenuse squared.

### Why does the formula a2 b2 C2 work?

The formula is A2 + B2 = C2, this is as simple as one leg of a triangle squared plus another leg of a triangle squared equals the hypotenuse squared. Hypotenuse- In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle.

### How is the Pythagoras theorem written in math?

When a triangle has a right angle (90°) … and squares are made on each of the three sides. then the biggest square has the exact same area as the other two squares put together! It is called “Pythagoras’ Theorem” and can be written in one short equation: a 2 + b 2 = c 2.

How to draw Pythagoras theorem with pen and scissors?

Get paper pen and scissors, then using the following animation as a guide: Draw a right angled triangle on the paper, leaving plenty of space. Draw a square along the hypotenuse (the longest side) Draw the same sized square on the other side of the hypotenuse. Draw lines as shown on the animation, like this: Cut out the shapes.

Who was Pythagoras student who calculated value of √2?

After all, Pythagoreans worshipped numbers. And they maintained a cult-like devotion that proved not only legendary but deadly. Nobody understood this better than Pythagoras’s student, Hippasus. Hippasus calculated the value of √2, which was previously thought to be nonexistent.

## How is the Pythagorean theorem generalized to inner product spaces?

Inner product spaces. A further generalization of the Pythagorean theorem in an inner product space to non-orthogonal vectors is the parallelogram law : which says that twice the sum of the squares of the lengths of the sides of a parallelogram is the sum of the squares of the lengths of the diagonals. 02/08/2019
