Question

Which one of these statements correctly states Pythagoras' Theorem for the following diagram?

a) d 2 = e 2 − f 2
b) d 2 = e 2 + f 2
c) e 2 = d 2 + f 2
d) f 2 = d 2 + e 2

Answer 1

I couldn't really read the problem that well, but if there's an e^2+f^2=d^2, then that's probably the correct option.
