Studdy Solution
STEP 1
1. We are given that .
2. We need to prove that .
STEP 2
1. Use the given congruence to establish congruent parts.
2. Identify congruent segments using CPCTC (Corresponding Parts of Congruent Triangles are Congruent).
3. Use properties of angles to establish congruence.
4. Apply the SAS (Side-Angle-Side) congruence postulate.
5. Use the property of parallel lines and alternate interior angles to conclude the proof.
STEP 3
Given: .
