Question

proofs are composed of statements and reasons. determine if each entry is a reason or a statement.

vertical angles of theorem
\\(\overleftrightarrow{pq}\\) bisects \\(\overline{rs}\\)
\\(\overline{ab} \cong \overline{bc}\\)
given
definition of midpoint
linear pair postulate
reflexive property
\\(m\angle abc = 90^{\circ}\\)
\\(\angle a\\) and \\(\angle d\\) are complementary angles
\\(\angle 1 \cong \angle 2\\)

Explanation:

Distinguish between statements and reasons in geometric proofs

A statement is a specific mathematical assertion or claim about a geometric figure (e.g., congruence, equality, bisecting relationships). A reason is a justification, definition, postulate, theorem, or property that supports why a statement is true.

Classify each given entry

• "Vertical Angles of Theorem" (likely a typo for "Vertical Angles Theorem"): Reason
• "\(\overleftrightarrow{PQ}\) bisects \(\overline{RS}\)": Statement
• "\(\overline{AB} \cong \overline{BC}\)": Statement
• "Given": Reason
• "Definition of Midpoint": Reason
• "Linear Pair Postulate": Reason
• "Reflexive Property": Reason
• "\(m\angle ABC = 90^\circ\)": Statement
• "\(\angle A\) and \(\angle D\) are complementary angles": Statement
• "\(\angle 1 \cong \angle 2\)": Statement
