attachment?
OpenStudy (xapproachesinfinity):
i can't see any attachment either?

OpenStudy (xapproachesinfinity):
oh man i hate when user attach docs
just snapshot the thing and post it
OpenStudy (anonymous):
it would be the 2nd answer

do not just give answers
HanAkoSolo (jamierox4ev3r):
Don't provide direct answers @SkaterBoyShawn
Basically, this question is asking you how many times you can fold the figure perfectly in halves.
OpenStudy (anonymous):
i though tit was 4 lines of syemtry
OpenStudy (xapproachesinfinity):
first let's understand what does line of symmetry to an object?
OpenStudy (anonymous):
ok

OpenStudy (xapproachesinfinity):
hmm actually 4 seems good to me
OpenStudy (anonymous):
right
HanAkoSolo (jamierox4ev3r):
so you could split the object up and down
OpenStudy (anonymous):
yes

those are your two first lines of symmetry
OpenStudy (xapproachesinfinity):
so basicallly line of symmetry cuts the object into identical mirror images
HanAkoSolo (jamierox4ev3r):
|dw:1433289507874:dw|
and you can do it twice diagonally
HanAkoSolo (jamierox4ev3r):
and what @xapproachesinfinity said is correct. If you can reflect the images perfectly along the line of symmetry, then the line of symmetry is valid
HanAkoSolo (jamierox4ev3r):
so 4 seems like a reasonable answer

well i guess @Jamierox4ev3r is doing great explaining this
i let him/her explain it :)
OpenStudy (anonymous):
so 4 is the naswer
HanAkoSolo (jamierox4ev3r):
4 lines of symmetry, yes
OpenStudy (xapproachesinfinity):
@princess1990 challenge
how many this figure has
|dw:1433289667240:dw|
OpenStudy (anonymous):
no answer never mind

Hint: All sides are equal
OpenStudy (xapproachesinfinity):
again just imagine that shape as piece of paper and you can tie it play with it
OpenStudy (anonymous):
2
OpenStudy (xapproachesinfinity):
hmm close
you missed one
OpenStudy (anonymous):
3

OpenStudy (xapproachesinfinity):
since all sides are equal you can have 3 line of symmetry
OpenStudy (xapproachesinfinity):
yes! it is 3

A quadrilateral has angles that measure 125°, 115°, and 65°.
What is the measure of the fourth angle?
