How many lines of symmetry does the following figure have? H There are no lines of symmetry There is one line of symmetry There are four lines of symmetry There are two lines of symmetry

OpenStudy (aayushi.somani):

figure?

OpenStudy (fionacndg):

The figure is the letter " H "

OpenStudy (fionacndg):

how do you know that?

OpenStudy (aayushi.somani):

i guess there is only one line of symmetry

OpenStudy (anonymous):

H has 2 lines of symmetry.

OpenStudy (aayushi.somani):

umm.. its just the center line! the second one?

OpenStudy (anonymous):

|dw:1406473202478:dw|

OpenStudy (fionacndg):

have heard people say it is the amount of time you can fold the figure.... and such like that

OpenStudy (anonymous):

the quality of being made up of exactly similar parts facing each other or around an axis.

OpenStudy (aayushi.somani):

huh.. parallel sides donot mean lines of symmetry..! its just one line of symmetry

OpenStudy (fionacndg):

so the answer would be, one line of symmetry?

OpenStudy (anonymous):

The sides of "H" are equal |dw:1406473327170:dw| do you see the 2 lines? The answer is 2

OpenStudy (fionacndg):

Okay so each line is a line of symmetry, they do not go in pairs then?

OpenStudy (anonymous):

The 2 are made up exactly the same because the definition of (Symmetry) is the quality of being made up of exactly similar parts facing each other or around an axis. Got it?

OpenStudy (anonymous):

No, do you see the 2 sides of "H" those 2 particular lines are EXACTLY the same. So that mean it has 2 lines that are the same. Get it?

OpenStudy (fionacndg):

I think so now

OpenStudy (anonymous):

For an example the letter X has to lines that are the same, understand now?

OpenStudy (fionacndg):

oh okay now i get it

OpenStudy (anonymous):

Alright, good.

OpenStudy (aayushi.somani):

the same lines donot mean line of symmetry.. it means the line which dives the figure into two equal parts.. and we can see only 1 such line

OpenStudy (anonymous):

@Kainui

OpenStudy (anonymous):

No, "We" can't see one such line. You can also google what "Symmetry" means if you do not know the definition means.

OpenStudy (aayushi.somani):

i might be wrong so let us check @Mashy please help

OpenStudy (anonymous):

two lines of symmetry line of symmetry is a line.. which you can think of as a mirror.. |dw:1406474122627:dw||dw:1406474165802:dw|
