Description
Given: Triangle ABC with AD/DB = CE/EB
Prove: LINE DE || LINE AC
What is the missing step in the proof number 8?
1. AD/DB = CE/EB ----------> given
2.AD/DB+1 = CE/EB+1 -------->
Addition Property of Equality
3.AD+DB/DB =CE+EB/EB ---------------> using common denominators
4. AB = AD + DB
CB = CE + EB
----------> segment addition
5.AB/DB =CB/EB ------> Substitution Property of Equality
6.angle ABC congruent to angle DBE ------------> Reflexive Property of Congruence
7.triangle ABC ~ triangle DBE ----------> SAS similarity criterion
8. MISSING PROOF? --------- > Corresponding angles of similar triangles are congruent.
