In congruent triangles, corresponding sides are equal in length. If triangle LIP is congruent to triangle STK, the corresponding sides can be matched as follows:
- Side LI corresponds to side ST
- Side IP corresponds to side TK
- Side PL corresponds to side KS
Therefore, the sets of sides that are corresponding and congruent are:
- LI ≅ ST
- IP ≅ TK
- PL ≅ KS
This means that each pair of corresponding sides has the same length.
