| − | The '''Pythagorean theorem''' is possibly the most well known mathematical theorem. It states that by taking the square of each length of a right angled triangle and adding them together you will get the length of the [[hypotenuse]] squared. This is expressed mathematically as: | + | The '''Pythagorean theorem''' is possibly the most well known mathematical theorem. It states that squaring the lengths of the two smaller sides of a [[right triangle]] and adding them together will get the length of the [[hypotenuse]] squared. This is expressed mathematically as: |
