Hi
How do you find the perimeter of triangle ABC on the Pythagorean theorem?
The pythagorean Theorem States:  a^2 + b^2 = c^2
that allows one to find a third side given the other two sides ...
which allows for finding the P = a + b + c
for example: if a = 3 and b = 4, the c = {{{sqrt(9+16) = 5}}}
 and therefore,   P = 3 + 4 + 5 = 12 units
