Given: δabc with prove: statementreason 1. given 2. addition property of equality 3. using common denominators 4. ab = ad db cb = ce ebsegment addition 5. substitution property of equality 6.reflexive property of congruence 7. δabc ~ δdbesas similarity criterion 8. ∠bac ≅ ∠bdecorresponding angles of similar triangles are congruent. 9. if the corresponding angles formed by two lines cut by a transversal are congruent, then the lines are parallel. 16 what is the missing step in this proof?
a. ∠abc ≅ ∠dbe
b. ∠bca ≅ ∠bde
c. ∠acb ≅ ∠deb
d. ∠bde ≅ ∠ade
e. ∠cab ≅ ∠dac]
