Not necessarily. A rhombus is an equilateral quadrilateral but does not have a line of symmetry. An irregular octagon does not, either.
An octagon is a 2-dimensional figure, not a line of symmetry. However, it has several lines of symmetry.
A regular octagon has 8 line of symmetry.
Yes.
Yes. Any equilateral shape can have both rotational and line symmetry.

An octagon is a 2-dimensional figure, not a line of symmetry. However, it has several lines of symmetry.
An equilateral triangle has both line symmetry and rotational symmetry. A non-equilateral isosceles triangle has line symmetry but not rotational symmetry. A scalene triangle has neither kind of symmetry.
A regular octagon has 8 line of symmetry.
Yes.
Yes. Any equilateral shape can have both rotational and line symmetry.
A regular octagon has 8 lines of symmetry and one center point of symmetry An octagon can also have fewer lines of symmetry: 0, 2 or 4 .

A kite or an equilateral trapezium.
An equilateral triangle and an isoceles triangle have one line of symmetry.
Yes it has three.
yes
Some triangles do have a line of symmetry. Equilateral and Isosceles triangles have a line of symmetry. If you can fold a triangle into two equal halves, the folding line is a line symmetry.
