just to clear things up so it didn't confuse anyone .

4. ganeshie8

so, in step 2 you proved one set of ANGLEs are congruent

5. ganeshie8

and in step3 you proved second set of ANGLEs are congruent

6. ganeshie8

you have TWO sets of ANGLES that are congruent. which similarity theorem you may use for justification ?

8. alainabbyboo22

there , this one is clearer to see .

9. ganeshie8

wow good work :)

10. alainabbyboo22

thanks :) alright now looking at what you said !!

11. ganeshie8

ok. . :)

12. alainabbyboo22

hm .. i wanna go with option A.

13. alainabbyboo22

is that incorrect though ?

14. ganeshie8

we have only 2 ANGLES that are congruent, we dont knw about SIDES right ?

15. alainabbyboo22

true !! so option C or D is what i need to focus on

16. alainabbyboo22

D

17. ganeshie8

yes last one is the correct one, AA similarity. great work :D

18. alainabbyboo22

thanks !! (:
