How many lines of symmetry does the following figure have? A.1 line of symmetry B.2 lines of symmetry C.3 lines of symmetry D.An infinite number of lines of symmetry

OpenStudy (anonymous):

Sorry it's a bit blurry, but yeah it's just a rectangle.

OpenStudy (anonymous):

what do you think the answer is?

OpenStudy (anonymous):

Either A or D?

OpenStudy (anonymous):

Think you could upload it again but better? But if you know what symmetry is you can figure it out without us. How could it be D though?

OpenStudy (anonymous):

Cause you could fold it up many times, and it's basically just a vertical rectangle.

that picture looks like a blurry door in the distance

OpenStudy (anonymous):

Yeah that's basically it,

OpenStudy (anonymous):

line of symmetry is basically a line you can draw through a shape that both sides of the line will look the same

OpenStudy (anonymous):

Well you could fold it vertical and horizontally . But I don't see anymore ways.

OpenStudy (anonymous):

oh okaaay

OpenStudy (jdoe0001):

what about diagonally?

OpenStudy (anonymous):

okaay

OpenStudy (anonymous):

and can you fold a rectangle diagonally ? @jdoe0001

OpenStudy (anonymous):

another why to thinkof line of symmetry is if you fold the shape along the line of symmetry, the 2 halves will match up or line up

OpenStudy (jdoe0001):

after you flip one of the sides, you can tuck it to the other origin symmetry shows up that way

OpenStudy (anonymous):

if you fold the rectangle diagonally, you will get something that looks like |dw:1376254514660:dw|

OpenStudy (anonymous):

@Mhm120 No.

OpenStudy (anonymous):

So does that mean there are 3 lines of symmetry?

OpenStudy (anonymous):

I don't see a third.

OpenStudy (anonymous):

so it's 2?

OpenStudy (anonymous):

Thats what I think.

OpenStudy (anonymous):

Okay i'll just put 2. :)
