Many figures. For example, an ellipse.
No. A square is a plane figure and conventionally for plane figures symmetry is considered in terms of rotation about a point or an axis (in the plane of the figure) but not a plane outside the plane of the square.
A figure that has matching parts when divided by a line is said to have a line of symmetry. These figures are also called symmetrical and their center of gravity lies along the line of symmetry.
A square has one distinct geometric figure, which is itself. However, it can also be associated with various mathematical concepts, such as its area and perimeter, but these do not count as separate figures. In terms of symmetry, a square has four lines of symmetry and rotational symmetry of order 4.
Square, hexagon, octagon, rectangle, bowtie-shaped figure, etc.
Figures that have rotational symmetry include circles, regular polygons (like squares, equilateral triangles, and hexagons), and three-dimensional shapes such as spheres, cylinders, and cones. A figure exhibits rotational symmetry if it can be rotated around a central point by a certain angle and still look the same as it did before the rotation. The angle of rotation depends on the figure; for instance, a square has rotational symmetry at 90-degree intervals, while a circle has infinite rotational symmetry.
A line of symmetry divides a figure into two matching halves.
A figure has rotational symmetry if you can turn it about a figure.
The order of rotation of a geometrical figure refers to the number of times it can be rotated to look the same within a full 360-degree rotation. The number of axes of symmetry is the number of lines that can be drawn through the figure such that each side is a mirror image of the other. Generally, figures with higher orders of rotation tend to have more axes of symmetry, as rotational symmetry often implies reflective symmetry. However, this is not a strict rule, as some shapes may possess high rotational symmetry yet fewer axes of symmetry.
yes
square
The letters S and N have point symmetry but not line symmetry.
