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.
An equilateral triangle has 3 lines of symmetry
It has 3 lines of symmetry
Only if it is an equilateral triangle which has 3 equal sides and 3 lines of symmetry
An equilateral triangle has 3 lines of symmetry
It can do. It can have 0, 1, 2, 3 or 6 lines of symmetry.
If it's a regular octagon , it's having 8 lines of symmetry .
A scalene triangle, A trapezoid, an irregular pentagon.
Well i cant think of any shape without a line of symmetry that isn't irregular. * * * * * Most shapes do not have any line of symmetry. Your hand, for instance, or each eye. Your face, if viewed at sufficient detail, is asymmetric.
Only equilateral triangles and some irregular polygons of (3n) sides have 3 lines of symmetry. A regular polygon with n sides (or vertices) has n lines of symmetry. If n is even, there are n/2 lines of symmetry from vertex to opposite vertex and another n/2 from the middle of a side to the middle of the opposite side. If n is odd, there are n lines of symmetry from vertex to the midpoint of the opposite side.
