Answer: Law of syllogism
Step-by-step explanation:
Since she is given that ∠1 and ∠2 are vertical angles.
⇒∠1=∠2 [ Since she knows that if two angles are vertical, they are congruent. ]
⇒ m∠1 = m∠2[Since she knows that if two angles are congruent, then they have the same measure.]
Therefore by law of syllogism, if ∠1 and ∠2 are vertical angles then m∠1 = m∠2.
The law of syllogism is a valid argument form of deductive reasoning .It is similar to the transitive property of equality, which reads: if a = b and b = c then, a = c.
