A point of symmetry refers to a specific point in a geometric figure where the figure is mirrored or balanced around that point. When a shape is rotated 180 degrees around this point, it appears unchanged, meaning each part of the figure has a corresponding part at an equal distance on the opposite side. This concept is often used in mathematics and physics to analyze shapes and patterns. Examples include the center of a circle or the centroid of a symmetric object.
It is a line through the point of symmetry. In general it is not an axis of symmetry.

A circle exhibits both line symmetry and point symmetry. It has an infinite number of lines of symmetry that pass through its center, dividing it into two mirror-image halves. Additionally, any point on the circle can be reflected through its center to another point on the circle, demonstrating point symmetry. This means that every point on the circle is equidistant from the center, reinforcing both types of symmetry.

No, a triangle does not have point symmetry. Point symmetry occurs when an object or shape remains the same after being rotated 180 degrees around a central point. In the case of a triangle, it does not have point symmetry because it does not look the same after a 180-degree rotation.

The letters S and N have point symmetry but not line symmetry.

No, a triangle does not have point symmetry. Point symmetry occurs when an object or shape remains the same after being rotated 180 degrees around a central point. In the case of a triangle, it does not have point symmetry because it does not look the same after a 180-degree rotation.
When an image has a point of symmetry, it means that for every point in the image, there is a corresponding point directly opposite it at an equal distance from the center point. Therefore, any line drawn through this central point will divide the image into two mirrored halves, making it a line of symmetry. This property holds true for various shapes, as their symmetrical characteristics are defined by their relationship to this central point. Thus, all lines through the point of symmetry serve as lines of symmetry.
Its extremum is on its axis of symmetry.

No, the centre of symmetry is a point usually somewhere in the middle of an object around which things like rotational or reflection occurs. Inversion symmetry is a sort of symmetry itself and not a point like the centre.
A 5 point star has 5 lines of symmetry.
True.
