To determine which theorem of triangle congruence shows that \(\triangle TUV \cong \triangle WVU\), we need to examine the given diagram and the marked congruencies:
1. \(\overline { TU} \cong \overline { WV} \)
2. \(\overline { TV} \cong \overline { WU} \)
3. \(\overline { UV} \) is a common side for both triangles.
Thus, the triangles \(\triangle TUV\) and \(\triangle WVU\) have three pairs of congruent sides:
- \(\overline { TU} \cong \overline { WV} \)
- \(\overline { TV} \cong \overline { WU} \)
- \(\overline { UV} \) (common side)
Since all three sides of one triangle are congruent to all three sides of another triangle, the correct congruence theorem is SSS (Side-Side-Side).
Supplemental Knowledge
Triangle congruence theorems are fundamental tools in geometry to prove that two triangles are congruent. The primary theorems include:
1. SSS (Side-Side-Side) Theorem: Two triangles are congruent if all three sides of one triangle are congruent to all three sides of another triangle.
2. SAS (Side-Angle-Side) Theorem: Two triangles are congruent if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle.
3. ASA (Angle-Side-Angle) Theorem: Two triangles are congruent if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle.
4. AAS (Angle-Angle-Side) Theorem: Two triangles are congruent if two angles and a non-included side of one triangle are congruent to two angles and a corresponding non-included side of another triangle.
