How many lines of symmetry does this figure have? [Note: The black ball is part of the figure.] A) 0 B) 1 C) 5 D) 10 E) infinitely many

@dude

Ideas? Usually a pentagon has 5 lines of symmetry but because of the black ball, it is limited

Thats the opposite of what I just said It's limited, not unlimited Try to make lines on the pentagon and see if the sides are equal |dw:1571501409138:dw|

`Usually a pentagon has 5 lines of symmetry but because of the black ball, it is limited`

ok C

@dude

Stop guessing I am telling you what to do, please read what you are told and perhaps you'll be able to get your answer on your own It is not 5 |dw:1571502362383:dw| It that equal on both sides?

yes

There are no lines of symmetry: |dw:1571503361547:dw|

Although the image is crude, look at the plotted lines of symmetry. How many of the lines split the figure into 2 symmetrical halves?

And by equal, dude means, is the shape mirrored on either side of the line.

If you folded it in half, would the sides match?

well since you put it like that, it wouldn't

Why? because of that black ball. So which of the plotted lines of symmetry actually split the shape in the described method.

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Gdeinward There are no lines of symmetry: Created with RaphaëlReply Using Drawing \(\color{#0cbb34}{\text{End of Quote}}\) THere are no lines of symmetry is inaccurate. Forget I said that.

0

Why do you think that?

oh wait my mistake

i believe it would only be 1

Okay, how did you arrive to this conclusion.

by the question you asked: How many of the lines split the figure into 2 symmetrical halves? i looked at the figure with the lines you did and i seen it would be only 1 split

You are correct. I just wanted to ensure that you understood the factors at play. You can see that the line |dw:1571504636919:dw|

cuts the ball into two equal halves. Otherwise, there are no other lines of symmetry that do this

ok i get it now, could you help check over more

sure, just do one question per post.

yes sir

i posted it

The figure has 1 line of symmetry, passing through the black ball from lower left to upper right.
