Pythagorean Theorem, its proofs and applications
Let us consider a triangle with one of the angles being right angled shown below in figure 1:
Figure 1
Such a triangle has a very special relationship between its sides in geometry. This relation was first
discovered by the Greek Mathematician-Philosopher Pythagoras, which is basically why it is named
after him.
The theorem states that the square of the side that is the hypotenuse (the side opposite to right
angle) is the sum of the other two sides. If we let the hypotenuse to be c and the other two sides to
be a and b we can represent this mathematically by;
c
2
= a
2
+ b
2
Proof:
Consider a the following square (exterior) is made up of 4 right-angled triangles below.
We can see that each side has length c which is the hypotenuse while each side of interior square
has length b a.
