Question

L and m are two parallel lines intersected by another pair of parallel lines p and q. show that ∆ ABC bisect ∆CDA. ​

Answer 1

Answer:

In △ABC and △CDA

∠BAC=∠DCA (Alternate interior angles, as p∥q)

AC=CA (Common)

∠BCA=∠DAC (Alternate interior angles, as l∥m)

∴△ABC≅△CDA (By ASA congruence rule)

answer is fully correct
