f^2 = a^2+b^2 = c^2
=>
f^2 = c^2
whats above property ?

reflexive says, a=a
which property is similar to below :
f^2 = a^2+b^2 = c^2
=>
f^2 = c^2

isnt it like,
If a = b and b = c then a = c.

thats right!
we are given two sides are congruent already, and we have just proven the third side f is also congruent.
so its SSS
you're Awesome :)
