If it is a regular 8 sided octagon then it will have 8 lines of symmetry
Different triangles may have none, one, or three lines of symmetry.
The shape of a flattened circle is called an ellipse. The shape is similar to an oval and some may mistakenly call it an oval.
An ellipse always has two axes of reflection; an oval has one or more.So, an egg-shape is an oval, but not an ellipse.In short an ellipse is an oval, but an oval may or may not be an ellipse.

They may have no lines of symmetry or they may have some - it all depends upon the shape of the irregular octagon. Only regular octagons have 8 lines of symmetry.
It may have none, depending on its shape; the maximum is three.
It may have none, depending on its shape; the maximum is three.
A dodecagon has 12 sides, and the number of lines of symmetry it possesses depends on the specific characteristics of the shape. A regular dodecagon, where all sides and angles are equal, has 12 lines of symmetry. Each line of symmetry passes through a vertex and the midpoint of the opposite side. Irregular dodecagons may have fewer lines of symmetry, determined by their unique properties.

One or none.
Different triangles may have none, one, or three lines of symmetry.
The shape that has no lines of symmetry and 2 pairs of parallel sides is a trapezoid. A trapezoid is a quadrilateral with at least one pair of parallel sides, and it does not have any lines of symmetry due to its asymmetrical nature. The two non-parallel sides of a trapezoid are typically of different lengths, further emphasizing its lack of symmetry.
Only if its in the form of an equilateral triangle or a isosceles triangle will it have lines of symmetry.
A regular octagon has 8 lines of symmetry. See the Related Link below that includes a diagram of an octagon with the lines of symmetry drawn. A non-symmetrical octagon may have between 0-4 lines of symmetry.
The shape of a flattened circle is called an ellipse. The shape is similar to an oval and some may mistakenly call it an oval.
This varies according to the polygon. A polygon is any 2D closed shape with three or more straight sides. Therefore, a polygon such as a square will have four lines of symmetry, but an irregular hexagon may have several or none. Even a triangle can have between zero and three lines of symmetry, depending on the type of triangle it is.
