A TriangleAns 2.An equilateral triangle has three axes of symmetry.A scalene triangle has none.An isosceles triangle is the only triangle with exactly one axis of symmetry.Whether an isosceles triangle qualifies as non irregular depends on your definition of regular.If the definition adopted allows an isosceles triangle to be regular, than any equilateral polygon can be converted into a figure that satisfies the question simply by increasing or decreasing the length of just one side by a small amount, symmetrically about its midpoint.The axis of symmetry will be the perpendicular bisector of the side whose length was changed.
