1 point

EF = MN.

DF=LN.

DE= LM.

all of these



​

Answer 1

Answer:

b is correct

Step-by-step explanation:

please follow me I will give you so much thanks only follow me

Answer 2

Step-by-step explanation:

In △LMNand △PNM

LM = PN (Given)

LN = PM (Given)

MN = NM (Common)

By SSS test of congruency

△LMN ≅ △PNM

∠L = ∠P (corresponding angles of congruent triangles)

∠LMN = ∠PNM (corresponding angles of congruent triangles)

∠MNL = ∠NMP (corresponding angles of congruent triangles)
