Question

given: ∠lkm = ∠jkm, ∠lmk = ∠jmk. prove: △lkm ≅ △jkm. choose the word that completes the sentence correctly. proof: ∠lkm ≅ ∠jkm and ∠lmk ≅ ∠jmk are given. km = km by the ____ property of congruence. transitive reflexive equivalence symmetric

Explanation:

The reflexive property of congruence states that any geometric figure is congruent to itself. Here, side $KM$ is the same side for both $\triangle LKM$ and $\triangle JKM$, so $KM\cong KM$ by the reflexive property.

Answer:

B. Reflexive
