Pythagorean Theorem
Pythagoras' Theorem was discovered by Pythagoras, a Greek mathematician and philosopher who lived between approximately 569 BC and 500 BC.
Pythagoras'
Theorem states that:
In
any right-angled triangle, the square of the hypotenuse is equal
to the sum of the squares of the other two sides. That is:
Pythagoras' Theorem in
Three Dimensions
A
three-dimensional object can be described by three measurements -
length, width and height.
We
can use Pythagoras' Theorem to find the length of the longest
straw that will fit inside
the
box or cylinder.
