which objects do not have rotational symmetry. One example would be fine, also could you tell me why it doesn't, thanks :-)
Generally speaking, an object with rotational symmetry is an object that looks the same after a certain amount of rotation.
Bicycle? Car? Animal? Person?
I hope this helps.
an object which does not have rotational symmetry
Objects that do not have rotational symmetry are those that, when rotated by any angle, do not appear the same as the original object. One example of such an object is the letter "L".
To understand why "L" does not have rotational symmetry, we can visualize it. Imagine drawing an "L" on a piece of paper. Now, try rotating the paper by any angle. No matter how much you rotate it, the "L" shape will never appear the same as the original. This is because the "L" has a distinct orientation with a clear distinction between the vertical and horizontal lines.
So, the absence of rotational symmetry in the letter "L" is due to its angular structure and lack of symmetry in its design.
