Reason
Statement
1. AABC is similar to ACED.
given
2. ABEBE
3. ABEBE
definition of slope
4. slope of AC = AB
definition of slope
slope of
DC = BE
5. slope of ΓΔ x slope of DC = Expe multiplying the slopes
6. slope of AC * slope of
DC EC DE
Substitution Property of Equality
7. slope of AΔ x slope of DC =-1 simplifying the right side
=- DEXEC
