No!

jimthompson5910 (jim_thompson5910):

I'm assuming the first two lines were given on another sheet or somewhere else (I don't see them given on this image attachment)

OpenStudy (anonymous):

Yes I talked to my teacher about the sheet and she gave me those.

jimthompson5910 (jim_thompson5910):

reason 6 is incorrect

jimthompson5910 (jim_thompson5910):

so is reason 7

OpenStudy (anonymous):

How should I go about fixing those?

jimthompson5910 (jim_thompson5910):

you'll need to use a triangle congruence property for reason 6

jimthompson5910 (jim_thompson5910):

triangle congruence properties SSS SAS ASA AAS

OpenStudy (anonymous):

How would I know which one, when none of them are marked?

jimthompson5910 (jim_thompson5910):

|dw:1449875850667:dw|

jimthompson5910 (jim_thompson5910):

these two angles are congruent |dw:1449875876681:dw| this is line 4 of your proof

jimthompson5910 (jim_thompson5910):

so are these two angles |dw:1449875901498:dw| this is line 5

jimthompson5910 (jim_thompson5910):

line 3 says we have these two congruent segments |dw:1449875942075:dw|
