HELP ASAP please and thank you! (Explain/show work please): Prove that the two triangles are congruent using the SAS congruence criteria. Show your work.

Triangle DEF: D(3,2), E(5,3), F(4,5)

Triangle FGH: F(4,5), G(3,7), H(5,8)

Given: ∠DFE and ∠GFH are vertical angles

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
