Question

Suppose △DEF≅△MNO. Which congruency statement is true?

EF

¯¯¯¯¯ ≅ MN ¯¯¯¯¯¯¯ DE ¯¯¯¯¯ ≅ MN ¯¯¯¯¯¯¯ DF ¯¯¯¯¯ ≅ NO ¯¯¯¯¯¯ EF ¯¯¯¯¯ ≅ MO ¯¯¯¯¯ ¯

Answer 1

DE≅MN

Explanation:

We know that corresponding parts of congruent triangles are congruent (CPCTC). Using the congruence statement we can match up the corresponding sides.

From the statement, ∠D matches ∠M, ∠E matches ∠N, and ∠F matches ∠O.

We also see that DE matches MN, EF matches NO, and DF matches MO.

Thus we have that DE≅MN.

Answer 2

△DEF≅△MNO

answer

DE≅MN
