# Geometry Class work , i need help please

**Question 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.
