0 Guest Posted January 8, 2009 Report Share Posted January 8, 2009 one. you can only cut a circle in half one way.Interesting - but first you have to chose where - E - W N - S etc BTW pls use a spoiler when 'ADD REPLY' an infinite numberwhy not RMZ - 1st answer tilted 90 degrees?

How many lines of symmetry does a circle have? on whether circle and lines lie in the same plane. If they are in the same plane, there are infinite lines of symmetry. However if planes are normal, there is a single line of symmetry. Anywhere in between will depend on angle of incidence between the planes. Now my head hurts Quote Link to comment Share on other sites More sharing options...

0 Guest Posted January 9, 2009 Report Share Posted January 9, 2009 A circle has an infinite number of lines of symmetry. Period. that the circle lies in the xy plane and you are drawing a line in the z plane. Then there is a single line of symmetry (an axis through the center of the circle) Quote Link to comment Share on other sites More sharing options...
0 bonanova Posted January 9, 2009 Report Share Posted January 9, 2009 Anywhere in between will depend on angle of incidence between the planes. Now my head hurts In between, for any angle other than 0 or 90 degrees, it's 360 degree [full rotational] symmetry. Or no symmetry; since every object reappears unchanged after 360 degree rotation.

0 Guest Posted January 9, 2009 Report Share Posted January 9, 2009 Well, lets say its a perfect circle, then that would mean that all sides are equal there for it would have an infinite amount of synnetry lines, or a leaast a really high amount of them.

0 Guest Posted January 9, 2009 Report Share Posted January 9, 2009 infinite... any diameter is a line of symetry and since line has no real width, you can draw an infinite number of lines that bisect the circle. Quote Link to comment Share on other sites More sharing options...
0 Guest Posted January 9, 2009 Report Share Posted January 9, 2009 that the circle lies in the xy plane and you are drawing a line in the z plane. Then there is a single line of symmetry (an axis through the center of the circle) it has an infinite number of lines of symmetry in the xy plane alone, so it has an infinite number.

0 Guest Posted January 9, 2009 Report Share Posted January 9, 2009 it has an infinite number of lines of symmetry in the xy plane alone, so it has an infinite number. I agree completely. My intention was simply to point out that planar orientation has an effect. Quote Link to comment Share on other sites More sharing options...
