A diamond symbol has two lines of symmetry.
A circle has infinite lines of symmetry, any line going through the center is a line for symmetry.
if all of the side are equal to each other, then it will have rotational symmetry. this means that if you stick a line through it and goes through the center, then it is a line of symmetry. the answer is infinity.
It has 1 line of symmetry through its vertical center
A circle has infinitely many points of symmetry. Every straight line that passes through the center of a circle is a line of symmetry.
The Isosceles triangle only has one possible line of symmetry; and that is through the vortex, AKA: The middle, in a vertical line.
One line of symmetry
There are an infinite number of lines of symmetry in a circle, as any diameter will be a line of symmetry and there are an infinite number of angle measure for that line to pass through.
I would think there would be an infinite number of lines of symmetry. Any line passing through the center of the circle, regardless of the angle will be a symmetry line.
It has 1 line of symmetry
Oh, dude, the letter D has only one line of symmetry. It's like looking in a mirror and seeing half of a D staring back at you. So, if you fold it in half along that line, it's like you're playing a fun little symmetry game with a letter. Cool, right?
There are infinitely many lines of symmetry. Every line can be a line of symmetry for a suitable shape.
