Hi there!

The correct answer is option D - Daniel is correct. This is because when proving a theorem congruent, you cannot use the theorem to prove itself. In her proof, Kelly used the theorem. 

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Answer:

C.) Daniel is correct

Step-by-step explanation:

In Daniel's proof, he wrote down each angle that was vertical to the other. He was able to correctly write the statements and give the right corresponding justification. Kelly, on the other hand, had only wrote down the theorem. She did not mention any properties to justify her proof, thus, she is incorrect. That leaves us with the answer choice, C.) Daniel is correct.
