oh man i hate when user attach docs just snapshot the thing and post it
anonymous
  • anonymous
it would be the 2nd answer
xapproachesinfinity
  • xapproachesinfinity
do not just give answers

Don't provide direct answers @SkaterBoyShawn Basically, this question is asking you how many times you can fold the figure perfectly in halves.
anonymous
  • anonymous
i though tit was 4 lines of syemtry
xapproachesinfinity
  • xapproachesinfinity
first let's understand what does line of symmetry to an object?
anonymous
  • anonymous
ok
Jamierox4ev3r
  • Jamierox4ev3r
|dw:1433289397901:dw|
xapproachesinfinity
  • xapproachesinfinity
hmm actually 4 seems good to me
anonymous
  • anonymous
right
Jamierox4ev3r
  • Jamierox4ev3r
so you could split the object up and down
anonymous
  • anonymous
yes
Jamierox4ev3r
  • Jamierox4ev3r
|dw:1433289474760:dw| those are your two first lines of symmetry
xapproachesinfinity
  • xapproachesinfinity
so basicallly line of symmetry cuts the object into identical mirror images
Jamierox4ev3r
  • Jamierox4ev3r
|dw:1433289507874:dw| and you can do it twice diagonally
Jamierox4ev3r
  • 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
Jamierox4ev3r
  • Jamierox4ev3r
so 4 seems like a reasonable answer
xapproachesinfinity
  • xapproachesinfinity
well i guess @Jamierox4ev3r is doing great explaining this i let him/her explain it :)
anonymous
  • anonymous
so 4 is the naswer
Jamierox4ev3r
  • Jamierox4ev3r
4 lines of symmetry, yes

@princess1990 challenge how many this figure has |dw:1433289667240:dw|

Hint: All sides are equal
xapproachesinfinity
  • xapproachesinfinity
again just imagine that shape as piece of paper and you can tie it play with it
anonymous
  • anonymous
2
xapproachesinfinity
  • xapproachesinfinity
hmm close you missed one
anonymous
  • anonymous
3
xapproachesinfinity
  • xapproachesinfinity
since all sides are equal you can have 3 line of symmetry
xapproachesinfinity
  • xapproachesinfinity
yes! it is 3

A quadrilateral has angles that measure 125°, 115°, and 65°. What is the measure of the fourth angle?
Jamierox4ev3r

|dw:1433290036342:dw|
xapproachesinfinity
  • xapproachesinfinity
interior angles in quad sum up to 360
xapproachesinfinity
  • xapproachesinfinity
see what is needed to complete 360
anonymous
  • anonymous
so the answer is 360
anonymous
  • anonymous
i say 2 if thats ok
xapproachesinfinity
  • xapproachesinfinity
no i said all angles add up to 360 can't have one that is 360

xapproachesinfinity
  • xapproachesinfinity
sum up those angles that they give you and see what you need to reach 360
anonymous
  • anonymous
305
xapproachesinfinity
  • xapproachesinfinity
how much you need to reach 360
anonymous
  • anonymous
55
xapproachesinfinity
  • xapproachesinfinity
yes
