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
