| Term | Definition |
|---|---|
| corrspondence | any way of pairing up the vertices between two geometric figures |
| congruence correspondence | correspondence that matches the vertices of geometric figures so that all pairs of corresponding parts are congruent |
| congruent triangles | triangles are congruent if and only if all of their corresponding parts are congruent |
| side-side-side (sss) Triangle congruence (postulate) | If each side of one triangle is congruent to the corresponding side of another triangle, then the triangles are congruent. |
| side-angle-side (sas) Triangle congruence (postulate) | If two sides and the included angle of one triangle are congruent to the corresponding sides and included angle of another triangle, then the two triangles are congruent. |
| angle-side-angle (asa) Triangle congruence (postulate) | If two angles and the included side of one triangle are congruent to the corresponding angles and included side of another triangle, then the two triangles are congruent. |
| side-angle-angle (saa) triangle congruence (postulate) | If two angles and a side opposite one of them in one triangle are conguent to the corresponding angles and side of another triangle, then the two triangles are congruent. |
| CPCTC | Corresponding Parts of Congruent Triangles are Congruent |
| Reflexive property | A figure is congruent to itself |
| symmetric property | If figure A is congruent to figure B, then figure B is congruent to figure A. |
| transitive property | If figure A is congruent to figure B and figure B is congruent to figure C, then figure A is congruent to figure C. |
