If it's a regular octagon , it's having 8 lines of symmetry .
An equilateral triangle has exactly 3 lines of symmetry.
If it is irregular most likely not. I know it is possible to have 2 lines of symmetry but I'm not so sure about 3 lines. Maybe you can figure it out by drawing it for yourself.
no.
An equilateral triangle contains at least 2 lines of symmetry (it actually contains 3 lines of symmetry). An equilateral triangle is also radially symmetric.If the question is "Is there a triangle with exactly 2 lines lines of symmetry?", the answer is no.
