he figure below shows two polygons. Gabrielle said that both are irregular convex polygons. Is Gabrielle correct? Yes, all the sides are not of the same length in both. Yes, all the angles are not of the same measure in both. No, polygon A is regular because all interior angles measure the same. No, polygon A is concave because it has two angles that measure greater than 180 degrees.

OpenStudy (anonymous):

I think it is a or b.. what do y'all think?

OpenStudy (eyust707):

this one?

OpenStudy (anonymous):

yup! I think it is a or b..but i am nt sure!

OpenStudy (eyust707):

okay so to tdo this one you need to know what an irrgular polygon is and what a regular polygon is

OpenStudy (anonymous):

an irregular polygon is a polygin with no sides or angles that are equal

OpenStudy (eyust707):

yes!

OpenStudy (anonymous):

a regular polygin has the same sides and angles that are equal

OpenStudy (anonymous):

so I got that, what should I do next?

OpenStudy (eyust707):

now you look at the picture. do either of those shapes appear to be regular?

OpenStudy (anonymous):

no they are not regular

OpenStudy (eyust707):

why not?

OpenStudy (eyust707):

that is correct btw

OpenStudy (anonymous):

because the first shape has an angle that is not the same with the other ones, and it only has two same sides, while the second polygon you dont know if it has same sides or angle because it does not indicate

OpenStudy (eyust707):

ahh i see the issue

OpenStudy (eyust707):

so we have to read the answers very carefully

OpenStudy (eyust707):

only one of them is fully true!

OpenStudy (anonymous):

yea thats the tricky part,

OpenStudy (anonymous):

ok let me read them carefully

OpenStudy (eyust707):

|dw:1339089024410:dw|

OpenStudy (anonymous):

so this means it is not a

OpenStudy (anonymous):

so polygon A is convex

OpenStudy (eyust707):

correct

OpenStudy (anonymous):

so the answer is C?

OpenStudy (eyust707):

oh im sry it is A

OpenStudy (eyust707):

all the angles of the first one are the same so that cant be the reason

OpenStudy (anonymous):

alright hold on i will be back

OpenStudy (eyust707):

but if you look for both shapes all the sides are of different length

OpenStudy (anonymous):

so it is A? then?
