only c





Symmetric figure will appear balanced on either side of its line of symmetry. 2types. reflection symmetry %26amp; rotation symmetry. Line symmetry is where u can draw a line that acts like a mirror, across a picture %26amp; both sides look exactly the same %26amp; the line is called the line of symmetry. An image has rotational symmetry if there is a point in the image that the image can be turned around a certain no of degrees %26amp; still look the same. No of times a shape looks exactly the same through full rotation of 360* is called order of rotational symmetry.
Reply:rotational symmetry means the figure can be rotated by angle less than 360 degree and end up looking exactly the same. If you rotate . ÷ by 180 degrees you get . ÷ back again. If you rotate % by 180 degrees you % back again. If you rotate %26gt; 180 degrees you get %26lt;. So %26gt; is not rotationally symmetric.





Take a look at this page and you will get the hang of it:

Reply:b and c
Reply:b and c because it is
Reply:band c


Both look the same upside down, a 180 degree rotation.
Reply:i believe only c.. it is defiantly not two of them , the are all too different.
Reply:b and c





they can be rotated 180 degrees.





a cannot be rotated.
Reply:b and c.
Reply:a and b.





c, when rotated, is identical. but you're not looking for identical, your looking for symmetrical (mirror image)
