Question

Which lines in the following proof of △ABC≅△CDA have the correct justification? Select all that apply.

Options:
A. AC≅AC, Reflexive Property of Congruence
B. ∠ACB≅∠CAD, Alternate Interior Angles Theorem
C. ∠BAC≅∠DCA, Alternate Interior Angles Theorem
D. △ABC≅△CDA, SAS Triangle Congruence Theorem

Answer 1

A and B and C

theres another answer right here that explains why

Answer 2

• A, B, C

Explanation:

Options:

A. AC≅AC, Reflexive Property of Congruence

• Correct. This is shared side of the triangles ABC and CDA

B. ∠ACB≅∠CAD, Alternate Interior Angles Theorem

• Correct. BC and AD are parallel and AC is transversal

C. ∠BAC≅∠DCA, Alternate Interior Angles Theorem

• Correct. AB and DC are parallel and AC is transversal

D. △ABC≅△CDA, SAS Triangle Congruence Theorem

• Incorrect. This should be ASA as we have shown above the angles A and C and included side AC are congruent.
