Answer:
1. [tex]\overline {TU}[/tex]
2. Given
3. [tex]\overline {RT}[/tex]
4. Side-Side-Side (SSS) rule of congruency
Step-by-step explanation:
The two column proof is presented as follows;
Statement [tex]{}[/tex] Reason
1. [tex]\overline {RS}[/tex] ≅ [tex]\overline {TU}[/tex] [tex]{}[/tex] Given
2. [tex]\overline {ST}[/tex] ≅ [tex]\overline {UR}[/tex] [tex]{}[/tex] Given
3. [tex]\overline {RT}[/tex] ≅ [tex]\overline {RT}[/tex] [tex]{}[/tex] Reflexive property
4. ΔRST ≅ ΔTUR [tex]{}[/tex] SSS rule of congruency[tex]{}[/tex]
The Side-Side-Side rule of congruency states that if three sides of one triangle are congruent to three sides of another triangle then both triangles are congruent.
