Answer: a. Transitive property.
Step-by-step explanation:
We can see that , Statement 2 , in the given proof says that ∠2 ≅ ∠3 and Statement 3 says that
∠2 ≅ ∠6
Then by using transitive property of congruence, we have
∠3 ≅ ∠6
Thus, the missing reason in the proof = Transitive property .
Hence, the correct answer is option (a.) transitive property.
- Transitive property of congruence says that if a ≅ b and b ≅ c then
a ≅ c.
