Which statement best explains the relationship between Triangle ABC and Triangle EDC? (4 points)

a
Triangle, because m∠3 = m∠6 and m∠1 = m∠4

b
Triangle ABC is congruent to triangle EDC, because m∠3 = m∠4 and m∠1 = m∠5

c
Triangle ABC is congruent to triangle EDC, because m∠3 = m∠6 and m∠1 = m∠4

d
Triangle ABC is similar to triangle EDC, because m∠6 = m∠2 and m∠3 = m∠4
