Question

In two triangle ABC and DEF, if ABˉ=EFˉ,BCˉ=DFˉ and CAˉ=DEˉ, then:\bar{AB} = \bar{EF} , \bar{BC} = \bar{DF} \space and \space \bar{CA} = \bar{DE}, \space then:​​

A.

ABCDEF\triangle ABC \cong \triangle DEF​​

B.

DEFBCA\triangle DEF \cong \triangle BCA​​

C.

BACFDE\triangle BAC \cong \triangle FDE​​

D.

CBADFE\triangle CBA \cong \triangle DFE​​

Correct option is D

Given:

AB=EF BC=DF CA=DE\overline{AB} = \overline{EF}\\ \ \\\overline{BC} = \overline{DF} \\ \ \\\overline{CA} = \overline{DE}

These conditions suggest that the corresponding sides of triangles ABC and DEF are equal.

Concept Used:

If the corresponding sides of two triangles are equal, then the triangles are congruent by the SSS (Side-Side-Side) congruency.

Solution:

Since AB=EF\overline{AB} = \overline{EF}​,  BC=DF\overline{BC} = \overline{DF}​, and  CA=DE\overline{CA} = \overline{DE}​, all corresponding sides of triangle ABC and triangle DEF are equal.

Therefore, by the SSS congruence, we can conclude that:

△CBA ≅ △DFE
