a square
an equilateral triangle
octagon
Only if it is an equilateral triangle which has 3 equal sides and 3 lines of symmetry
Irregular shapes have NO lines of symmetry and all the sides are not the same. A regular shape WILL have lines of symmetry and all the sides are the same. * * * * * Wrong! A kite, for example, is an irregular but it has reflective symmetry. A parallelogram is an irregular quadrilateral but has rotational symmetry.
