@jigglypuff314 ohai! Are you busy?

jigglypuff314 (jigglypuff314):

I can help :)

OpenStudy (anonymous):

Only one of these! And a two column proof! I can do the rest! ;3

jigglypuff314 (jigglypuff314):

a. XY (Definition of Parallelogram) b. CX (property of parallelogram?) CW c. WZY (property of parallelogram?) d. WY (diagonals of parallelograms bisect each other?) XZ e WZY or was it WXY? f. ZCY (vertical angles are congruent)

OpenStudy (anonymous):

Whats e?

jigglypuff314 (jigglypuff314):

either WZY or WXY would be correct... it was a property of parallelograms ;) I forget which :P

OpenStudy (anonymous):

Question marks for b and c?

jigglypuff314 (jigglypuff314):

idk the property names :P

OpenStudy (anonymous):

If I put just property of parallelogram would I get it wrong :O

OpenStudy (anonymous):

;3 Probably the last one I need for today :D I'm starting to get it ;3

jigglypuff314 (jigglypuff314):

1. DE || AB (Definition of Parallelogram) 2. DF || AB (Transitive Property???) 3. angle BAE = angle AEF (alternate interior angles are congruent) 4. angle AEF = angle FGC (property of parallelogram?) 5. angle FGC = angle BAE (Transitive Property)

OpenStudy (anonymous):

But aren't you supposed to end off with the thing you have to prove?

jigglypuff314 (jigglypuff314):

5. angle FGC = angle BAE (Transitive Property) angle G = angle A

OpenStudy (anonymous):

Great Thanks! Do you know the properties for the last one?
