Question

Refer to the figure given below, and tap on the correct statement.

Answer 1

In $\Delta EDF$ and $\Delta ECF$
ED = EC = 8.9 in
DF = CF = 4 in
EF = EF = 4 in (common side)

∴ $\Delta EDF\cong \Delta ECF$ (S-S-S congruency criterion)

When three sides of one triangle are equal to the corresponding three sides of another triangle, both the triangles are congruent by S-S-S criterion.
