If three sides of one triangle are congruent to three sides of a second triangle, the triangles are congruent

True

Explanation

This is called SSS Property

We can prove that the triangles shown below are congruent by the SSS property:

Since m(\( \overline{CD} \)) = 3 and m(\( \overline{ST} \)) = 3, the segments are congruent.

\( \overline{CD} \) ≅ \( \overline{ST} \)

Since m(\( \overline{DE} \)) = 4 and m(\( \overline{TR} \)) = 4, the segments are congruent.

\( \overline{DE} \) ≅ \( \overline{TR} \)

Since m(\( \overline{EC} \)) = 5 and m(\( \overline{RS} \)) = 5, the segments are congruent.

\( \overline{EC} \) ≅ \( \overline{RS} \)

Therefore, \( \triangle CDE \) ≅ \( \triangle STR \)
