Answer:
Step-by-step explanation:
From the figure attached,
Given:
Lines AB and CD are intersecting each other at a point E.
To prove:
∠ACB ≅ ∠DEB
              Statements                                 Reasons
1). ∠AEC + ∠BEC = 180°                        1). Linear pair theorem
2). ∠DEB + ∠BEC = 180°                       2). Linear pair theorem
3). ∠AEC + ∠BEC = ∠DEB + ∠BEC      3). Transitive property of equality
4). ∠AEC = ∠DEB                                  4). Subtraction property of equality
