Question

Fred and Victoria provide the following proofs for vertical angles to be equal:

Answer 1

Fred's proof: angle 2 + angle 3 = 180° (t is a straight line)
angle 1 + angle 2 = 180° (PQ is a straight line)
Therefore, angle 1 + angle 2 = angle 2 + angle 3 (Transitive Property of Equality)
Hence, angle 1 = angle 3 (Subtraction Property of Equality)

Victoria's proof: angle 1 + angle 4 = 180° (t is a straight line)
angle 1 + angle 2 =180° (PQ is a straight line)
Therefore, angle 1 + angle 2 = angle 1 + angle 4 (Transitive Property of Equality)
Hence, angle 2 = angle 4 (Subtraction Property of Equality)

Which statement is correct?

Both Fred's and Victoria's proofs are correct.
Both Fred's and Victoria's proofs are incorrect.
Only Fred's proof is correct
Only Victoria's proof is correct

Answer 2

ummmmmm well i know that they cant both be rong so u can take that out of the equation, and i know that freds is corect but i dont know about the other equation sorryy thats the best i can do.
