The fundamental
Hi guys, in this presentation I am going to be presenting Pythagoras' theorem in the most
pure and fundamental form so let us take a closer look here I have a right angle triangle
and remember we can only use Pythagorean theorem by if the triangle is at right triangle must
have the 90 degrees here joining two sides. So the first thing we are going to be is label
the pronumeral and we are going to write the actual theorem or the proof that Pythagoras'
postulated over 500 BC. So let us right up each side, so let us call this side across
here A, down here let us call this B, and the third side is often the longest sides
call that C. now that C, that C longest side is referred to as the hypotenuse it is a long word for a long side.
So on this triangle the actual formula or the equation for Pythagoras' theorem works
like this, it is actually the first length here a then it is squared plus the second
length here b and that is also squared finally the third length here c, equal c and that
also squared that is Pythagoras' theorem, a squared plus b squared equals c squared.
