Select the statement that is missing from the proof below showing that vertical angles formed by intersecting lines are congruent.
Statements Reasons
1. â ABD and â ABC form a linear pair,â CBE and â ABC form a linear pair 1. Definition of a linear pair
2. â ABD and â ABC are supplementary,â CBE and â ABC are supplementary 2. Linear pair postulate
3. mâ ABD + mâ ABC = 180°,mâ CBE + mâ ABC = 180° 3. Definition of supplementary
4. ? 4. Substitution Property of Equality
5. mâ ABD = mâ CBE 5. Subtraction Property of Equality
6. â ABDâ
â CBE 6. Definition of congruent angles
mâ ABD+ mâ ABC = mâ DBC
mâ ABD+mâ DBE = mâ ABE
mâ ABD+mâ ABC=mâ DBE+mâ EBC
mâ ABD+ mâ ABC = mâ CBE + mâ ABC
