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.

One or none.
Different triangles may have none, one, or three lines of symmetry.
Ah, what a happy little question! The shape you're thinking of is a scalene triangle. It doesn't have any lines of symmetry, but it does have rotational symmetry of order 4, which means it looks the same after being rotated 90 degrees four times. Isn't that just lovely?
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.

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.
A dodecagon has 12 sides, so it has 12 lines of symmetry. Each line of symmetry divides the dodecagon into two equal halves, making it look like a mirror image. So, if you're ever in doubt, just remember that a dodecagon is as symmetrical as a Kardashian selfie.
