Question

what type of proofs did they use?
candices proof is an indirect proof because
the last statement contradicts given information
each statement builds on logic from a previous statement
joels proof is
statements
candices proof
reasons

1. ( mangle aox

eq mangle cox )

1. by supposition
2. ( angle aod cong angle cob )
3. vertical angles theorem
4. ( mangle aod = mangle cob )
5. definition of congruence
6. ( mangle aod + mangle aox

eq mangle cob + mangle cox )

1. additional property of equality
2. ( mangle aox

eq mangle cox )

1. angle addition postulate

statements
joels proof
reasons

1. ( mangle dox = mangle box )
2. given
3. ( mangle aod + mangle aox = mangle cob + mangle cox )
4. angle addition postulate
5. ( angle aod cong angle cob )
6. vertical angles theorem
7. ( mangle aod = mangle cob )
8. definition of congruence
9. ( mangle aox = mangle cox )
10. subtraction property of equality

Explanation:

Answer:

Candice's proof is an indirect proof because the last statement contradicts given information. Joe's proof is a direct proof because each statement builds on logic from a previous statement.
