Which theorem or postulate can be used to show ABC CDA?
What theorem determines that ABC and CDA are congruent?
First show that ABC ≡ CDA using the SSS congruence test. | ||
Hence | ACB = CAD and CAB = ACD | (matching angles of congruent triangles) |
so | AD || BC and AB || DC | (alternate angles are equal.) |
