I need help with #2. Medal will be rewarded if work is shown or work is explained correctly and accurately.

@hartnn Please help here, thanks :)

OpenStudy (firejay5):

I tried to make the questions clear and focused, it's really hard, my camera sucks

hartnn (hartnn):

you need just the statements, right ? .....what i would have done is searched the net...

OpenStudy (firejay5):

Well it's in the highlighted part. I did Part A - D, I just needed them checked

OpenStudy (firejay5):

I really need help with letter E first, I think A - D are correct

hartnn (hartnn):

i think B should be if two lines and a transversal form corresponding angles that are congruent, then the two lines are parallel

OpenStudy (firejay5):

No your B is too complicated

hartnn (hartnn):

i couldn't find the inverse....is your inverse correct ?

OpenStudy (firejay5):

yes, because it makes more sense

OpenStudy (firejay5):

If the corresponding angle have the same measure, then the parallel lines are cut by a transversal

hartnn (hartnn):

naah, doesn't make sense to me ....at all....

hartnn (hartnn):

ok, and i got the inverse statement if parallel lines are NOT cut by........will NOT have the same measure

OpenStudy (firejay5):

Well you're thinking too hard look at the first link where I hightlighted everything in orange

hartnn (hartnn):

for the converse part ?

OpenStudy (firejay5):

You got B off of Yahoo Answers

hartnn (hartnn):

i searched how to find converse....and that happened to match with yahoo answers

OpenStudy (firejay5):

they are wanting the converse from the worksheet not from on-line, not saying you're wrong, but your converse of CAP is too complicated to comprehend

hartnn (hartnn):

when there's something like p-> q the converse will be q->p

OpenStudy (firejay5):

yes I am well aware of that

hartnn (hartnn):

p is : lines are parallel

OpenStudy (firejay5):

Let's work on E NOT B

hartnn (hartnn):

ok

OpenStudy (firejay5):

that's the one I don't have an answer for

hartnn (hartnn):

i would like to modify my inverse statement if non-parallel lines are cut by a transversal then corresponding angles will not have same measure we will validate this

hartnn (hartnn):

ok ?

OpenStudy (firejay5):

i got it

OpenStudy (firejay5):

how will we validate this and show illustrations for it

hartnn (hartnn):

by taking 2 non-parallel lines |dw:1378959624336:dw|

hartnn (hartnn):

so we should show that a is not = b|dw:1378959692928:dw|

hartnn (hartnn):

how did u prove the corresponding angles postulate ? we should use same method to validate this

OpenStudy (firejay5):

I used the same method you had, but moved my lines down more

hartnn (hartnn):

did u prove corr angles postulate using similar triangles?

OpenStudy (firejay5):

uh what are you talking about it

OpenStudy (firejay5):

I am not using triangles

hartnn (hartnn):

yeah, there r different methods...so if i would have used similar triangles to validate, you wouldn't get it... so thats why i asked how is that postulate proved in your text

OpenStudy (firejay5):

yea
