# SSS Congruence (Side-Side-Side Congruence)

How to solve SSS congruence problems: postulate, example and its solution (proof).

## Postulate

If three sides of a triangle are congruent to

three sides of another triangle,

then those two triangles are congruent.

## Example

Start from the given statements.

Two column proof

*C* is the midpoint of *BD*.

So *BC* ≅ *CD*.

*AC* is equal to itself.

So *AC* ≅ *AC*.

Three sides of △*ABC* are congruent to

three sides of △*ADC*.

Then, by the SSS congruence postulate,

△*ABC* ≅ △*ADC*.
