WILL FAN AND MEDAL GEOMETRY HELP QUICK

OpenStudy (legomyego180):

AH WHAT IS IT

OpenStudy (jolquinnzley):

Here is the question, I know nothing about proofs

OpenStudy (legomyego180):

Oh man everyone hates proofs. Let me see.

OpenStudy (mjdennis):

I think that this isn't a real geometry proof. Think 'demonstrate' instead of 'prove'. I assume, given this problem, that you should know how to write the equation of a line given two points? Do that, then use what you know about paralle lines to tell why the two lines are parallel.

OpenStudy (jolquinnzley):

I have no idea what that means. :/ Geometry is my absolute worst subject ever. Could you explain a little better please?

OpenStudy (legomyego180):

Im not sure how to do this

OpenStudy (jolquinnzley):

Still open to help!!!

OpenStudy (legomyego180):

Well, one way to think about it is if two lines are parallel then that means that their slope must be equal.

OpenStudy (jolquinnzley):

It does have to do with slope but we haven't talked about that yet. So, the answer has nothing to do with slope. The answer has to be a set of theorems and postulates that prove it but I don't know what ones prove it in a certain order.

OpenStudy (legomyego180):

This would be the proof you would need...\[\frac{ \frac{ y _{1} }{ 2 } -\frac{ y _{1} }{ 2 }}{ \frac{ x _{1}+x _{2} }{ 2 } } = \frac{ y _{1}-0 }{x _{1}-x _{2} }\]

OpenStudy (legomyego180):

This is a highschool geometry class?

OpenStudy (jolquinnzley):

Yes it is a highschool geometry class. I am taking a 10th grade class, I am in 9th grade about to finish. But thats a formula, not a proof.

OpenStudy (jolquinnzley):

In anycase, it's probably just something about the properties of a trapezoid so i think i got it. Since you were so nice, i'll fan and medal anyways. Have a nice evening!

OpenStudy (legomyego180):

Thanks. Good luck! Thats tough stuff for 10th grade.
