The most obvious one is the square. But it seems to me that
it's true for any regular polygon with an even number of sides.

No, line symmetry and diagonal symmetry are not the same. Line symmetry, also known as reflection symmetry, occurs when a figure can be divided into two equal halves that are mirror images of each other across a line. Diagonal symmetry, on the other hand, occurs when a figure can be divided into two equal halves that are mirror images of each other across a diagonal line. In essence, while both involve symmetry across a line, the orientation and positioning of that line differ between the two types of symmetry.
Lines of symmetry in polygons are not necessarily diagonals. A line of symmetry divides a shape into two identical halves, while a diagonal connects non-adjacent vertices of a polygon. In some cases, a diagonal can serve as a line of symmetry, but this is not true for all polygons. Therefore, while there can be overlap, the two concepts are distinct and not synonymous.
Yes. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.
No, take a semicircle, it is a plane figure and is open. Or a parabola is also open and a plane figure.

Line symmetric figures, also known as reflections or mirror images, are shapes that can be divided into two identical halves by a straight line, called the line of symmetry. When the figure is folded along this line, both halves match perfectly. Common examples include shapes like squares, rectangles, and certain triangles. The line of symmetry can be vertical, horizontal, or diagonal, depending on the figure.
right angled triangle
No. it can also be a rectangle
Vultures have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side. Which also means their eyes could see anything.
