Answer:
The correct option is;
(B) Triangles BCA and DAC are congruent according to the Angle-Side-Angle (ASA) Theorem.
Step-by-step explanation:
The given information are;
Lines AB and BC are parallel lines DC and AD respectively
AC constructed is congruent to AC (Reflexive property of equality)
∠BAC ≅ ∠DCA (Alternate angles theorem)
∠BCA ≅ ∠DAC (Alternate angles theorem)
Therefore, we have;
Triangle ΔBCA and triangle ΔDAC are congruent by Angle-Side-Angle (ASA) Theorem because, the congruent angles between ΔBCA and ΔDAC which are (∠BAC, ∠BCA in ΔBCA and ∠DCA and ∠DAC in ΔDAC) ∠BAC ≅ ∠DCA and ∠BCA ≅ ∠DAC are on opposite ends of the congruent line AC between the two triangles, therefore, we use the ASA Theorem
