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.
A kite or an equilateral trapezium.
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.
3 of each
If it is irregular enough, it may have not a single line of symmetry.
An equilateral triangle and an isoceles triangle have one line of symmetry.
yes
Yes it has three.
