Not necessarily. A rhombus is an equilateral quadrilateral but does not have a line of symmetry. An irregular octagon does not, either.
No, they cannot.
an octagon * * * * * An octagon need not have equal sides. For that it would have to be an equilateral octagon (though not necessarily regular).
No but they will make a hexagon
Octagonal An octagon has eight sides and eight angles, and is a two-dimensional shape. In an equilateral octagon, each side has a degree measure of 135.
Not necessarily. A rhombus is an equilateral quadrilateral but does not have a line of symmetry. An irregular octagon does not, either.
In an octagon, there are 20 equilateral triangles. Each side of the octagon can form two equilateral triangles with the adjacent sides, resulting in 8 equilateral triangles. Additionally, the diagonals of the octagon can form 12 more equilateral triangles. Therefore, the total number of equilateral triangles in an octagon is 8 + 12 = 20.

A rectangle is not always equilateral, although it is always equiangular. A rhombus is not always equiangular, but is always equilateral. A square is both equilateral and equiangular.
An equilateral triangle, a square, a rectangle, an octagon.
