Question

from this given statement, select the definition, property, postulate, or theorem that justifies the prove statement. given: $\triangle cdfcong\triangle gdf$ prove: $overline{cf}congoverline{gf}$

Explanation:

Since $\triangle CDF\cong\triangle GDF$, by the property that corresponding parts of congruent triangles are congruent, the corresponding sides $\overline{CF}$ and $\overline{GF}$ are congruent.

Answer:

Corresponding - parts of congruent triangles are congruent (CPCTC).
