You would use it after you had shown that two figures Uusually triangles) are congruent. Then you could sy that Corresponding parts of the two congruent figures are also congruent to each other.

It stands for "Corresponding Parts of Congruent Triangles are Congruent", so you can only use it AFTER stating the triangles are congruent. It is used to justify why angles or sides that you didn't use in creating the congruent triangles are congruent to each other.

( corresponding parts of congruent triangles, are congruent)
If u already proved that two triangles are congruent,then u use this if u want use the fact that one side or an angle in one is equal to the corresponding side or angle in the other.
