what is true about these 2 polygons

OpenStudy (saifoo.khan):

They don't exist.

OpenStudy (highschoolmom2010):

OpenStudy (saifoo.khan):

Oh. now they do.

OpenStudy (saifoo.khan):

Hey both are similar, maybe?

OpenStudy (highschoolmom2010):

yepp patience is a virtue :D

OpenStudy (highschoolmom2010):

however if they are similar i have to write a ratio proving them similar

OpenStudy (saifoo.khan):

LOl.

OpenStudy (saifoo.khan):

There two more things true about these two polygons. -They both are four sided figures. -They both are parallelograms.

OpenStudy (highschoolmom2010):

ok that i already assumed is but what i dont understand is how to form the ratio

OpenStudy (highschoolmom2010):

i think the ratio is 10:1.2 is that correct?

OpenStudy (anonymous):

I don't think so. Match up the angles to determine corresponding sides.

OpenStudy (highschoolmom2010):

wait i flipped values **** 5:1.2***

OpenStudy (anonymous):

That's more reasonable. I would suggest that you check the other corresponding sides to make sure the ratio is equal.

OpenStudy (anonymous):

Something doesn't look right. Are you sure they are similar?

OpenStudy (saifoo.khan):

I think they're similar because of 120* angles.

OpenStudy (highschoolmom2010):

@gypsy1274 no im not entirely sure on these

OpenStudy (anonymous):

I thought so too, but the proportion of the sides don't match.

OpenStudy (saifoo.khan):

True^

OpenStudy (anonymous):

No, congruent would be corresponding sides are equal - they are not equal or proportional.

OpenStudy (saifoo.khan):

Oh no.

OpenStudy (highschoolmom2010):

so not similar then

OpenStudy (anonymous):

So, the question is "What do we know?" You're right. I would say that we know they are not similar.

OpenStudy (anonymous):

We also know how many sides each figure has.

OpenStudy (highschoolmom2010):

yes

OpenStudy (anonymous):

Do you know if the sides are parallel?

OpenStudy (highschoolmom2010):

the opposite sides are parallel (parallelograms)

OpenStudy (anonymous):

I would say yes, but I don't remember the acceptable proof of that. I think just the opposing sides being congruent would be the proof.

OpenStudy (anonymous):

There is also something we know about the angles, I think.
