1. LA ≅ SA 1. Given
2. TA ≅ AT 2. Reflexive Property, which states that the mirror of oneself is the same measurement as itself.
3. ∠LAT ≅ ∠SAT
- TA ≅ AT (Reflexive property)
- SA ≅ LA (Given)
- TA is a angle bisector of ∠SAL (Definition of angle bisector). (CPCTC)
- ∠SAT ≅ ∠LAT (CPCTC)
4. ΔLAT ≅ ΔSAT (CPCTC) (Corresponding Parts of Congruent Triangles are Congruent).
