I am stuck with a question.

I need a shape with a rotational symmetry order of 1 and 3 lines of symmetry.

thanks any help would be great

Well, 3 lines of symmetry would seem to suggest a triangular shape, but according to Symmetry - Rotation:

**Is there Rotational Symmetry of Order 1 ?**

**Not really!**If a shape only matches itself**once**as you go around (ie it matches itself after one full rotation) there is really no symmetry at all, because the word "Symmetry" comes from*syn-*and**together***metron*and there can't be "together" if there is just one thing.)**measure**,

Try giving that as a response to your teacher/professor. ;)
