To prove the statements, we will use the properties of parallel lines and congruent triangles. Step 1: Identify the triangles and given information. We are given two triangles, ABC and EDC. From the problem statement and diagram: • AB DE (indicated by the arrows on the lines). • DC = CB (indicated by the single tick marks on the lines). Step 2: Prove that ABC is congruent to EDC. Consider ABC and EDC: 1. ACB = ECD (These are vertically opposite angles). 2. CB = DC (This is given in the problem statement). 3. ABC = EDC (These are alternate interior angles because AB DE and BD is a transversal). By the Angle-Side-Angle (ASA) congruence criterion, ABC EDC. Step 3: Use Corresponding Parts of Congruent Triangles are Congruent (CPCTC) to prove the required statements. Since ABC EDC: (1) The corresponding sides AC and CE must be equal. Therefore, AC = CE. (2) The corresponding sides AB and DE must be equal. Therefore, AB = DE. Send me the next one 📸
