Answer:

3. Vertical angles are congruent.

4. Transitive Property of Equality.

Explanation:

The missing reasons in the proof are:

Vertical angles are congruent,Transitive Property of Equality.

Here is the completed proof:

Statements Reasons

22 and 23 are supplementary. | Given

21 and 22 form a linear pair. | Definition of linear pair

21 and 22 are supplementary. | Vertical angles are congruent.

21 + 22 = 180° | Definition of supplementary angles

21 + 23 = 180° | Property of Substitution

21 = 180° - 23° | Property of Subtraction

21 = 157° | Property of Substitution

Therefore, 21 and 24 are supplementary.

The Transitive Property of Equality states that if A = B and B = C, then A = C. In this proof, we use the Transitive Property of Equality to show that 21 = 157°.
