A figure has rotational symmetry if you can turn it about a figure.
If its an isosceles triangle it has 1 line of symmetry but if its an equilateral triangle it has 3 lines of symmetry
The original figure and its image must be of the same size and the same orientation. That is, you should be able to get from the original to the image by moving the shape along the x-axis and the y-axis and nothing else. However, if the shape has rotational or reflective symmetry, there is no way that you can be sure that it has not been rotated or reflects (as appropriate).
tell whether the measure could represent the perimeter or the area of a figure
You can tell whether a number is divisible by 5 by looking at the last digit if there is no decimal point. If the last digit a 5 or 0 then it is divisible by 5. For example 365 or 400

You turn it a quarter to see if it still has a line of symmetry.

The Unicorn went to "WWW.YOUTUBE.COM." The Unicorn clicks thavideo "REBECCA BLACK-FRIDAY." The Unicorn Hears the song then died. R.I.P Lily The Unicorn. >.< ._.
i could tell by the look of her body ,that she new what symmetry was.
just talk to her. you'll probably figure out whether you click or not by just talking to her.
symmetry principles always tell us something important. They often provide the most valuable clues toward deciphering the underlying principles of the cosmos, whatever those may be. In this sense, therefore, symmetry is certainly fruitful. Whether or not some all-encompassing symmetry is the grand principle that will necessitate our "theory-of-everything" is still to be determined.
ok i will tell
A hexagon can have 0,1,2,3,4 or 6 (not 5) lines of symmetry.
A line of symmetry or its diagonal
