Question

If $\Delta ABC$ $\cong$ $\Delta DEF$ by SSS congruence, then, match the corresponding equal sides.

• A. DE
• B. EF
• C. FD

Answer 1

If three sides of one triangle are equal to the three sides of another triangle, then the two triangles are said to be congruent by S.S.S. congruence.
For $\Delta ABC\cong \Delta DEF$,
we have AB = DE, BC = EF and AC = DF in accordance with the definition of S.S.S. congruence CPCT condition.
