A square has four lines of symmetry.
A square has 4 lines of symmetry
not all shapes have lines of symmetry. one example is a triangle.
A regular hexagon has more than 4 lines of symmetry. Even number sided polygons that are regular and have more than 4 sides have more than 4 lines of symmetry. Circles have more than four lines of symmetry. Squares also have 4 lines of symmetry.
How many lines of symmetry does an equilateral triangle have?
No. Asymmetric shapes do not have any lines (or planes) of symmetry.
no
Ellipses and non-square rectangles have two lines of symmetry.

A circle (infinitely many). A regular polygon with 4 or more sides.
Circles and Ovals DO have lines of symmetry: a circle has an infinite number of them (each is a diameter of the circle) and an oval (ellipse) has two (one along the major axis, one along the minor axis). Shapes which have no lines of symmetry are irregular ones, eg scalene triangles, along with most parallelograms (ie parallelograms which are not rhombuses) and non-isosceles trapezia. Some irregular shapes can have lines of symmetry, eg irregular octagons can have 1, 2 or 4 lines of symmetry as well as no lines of symmetry, unlike a regular octagon which [always] has 8 lines of symmetry.
Three dimensional shapes, generally, don't have lines of symmetry, but a circle has an infinite number is symmetry lines. 3D shapes also don't have rotational symmetry either, but a circle has an infinite number of that as well.
