A group of three positive integers, that, once plugged into the Pythagorean Theorum satisfy the a^2+b^2=c^2, a and b existing as the two shorter sides or bases of the triangle, while the longest side or the hypotenuse equals c as shown:
b ex. a=3, b=4, c=5: 3^2+4^2=5^2 =>9+16=25 (NOTE: these three numbers can be substituted for any multiples of theses numbers.)
