Use the given plan to write a two-column proof of the Symmetric Property of Congruence.

Given: segment AB ≅ segment EF
Prove: segment EF ≅ segment AB
Plan: Use the definition of congruent segments to write segment AB ≅ segment EF as a statement of equality. Then use the Symmetric Property of Equality to show that EF=AB. So segment EF ≅ segment AB by the definition of congruent segments.
