Point Symmetry in Geometric Shapes
In various geometric shapes such as square, rectangle, parallelogram, circle, star, etc., we can observe the point symmetry which is discussed as follows:
Point Symmetry of Square/Rectangle
- Center: The center of point symmetry for a square or rectangle is the intersection point of its diagonals.
- Symmetry Check: When rotated 180° around this central point, the square or rectangle looks the same. Additionally, reflection across the center results in identical shapes on both sides.
Point Symmetry of Parallelogram
- Center: The point symmetry in a parallelogram lies at the intersection of its diagonals.
- Symmetry Check: Similar to a square or rectangle, a parallelogram exhibits point symmetry if rotating it 180° or reflecting it across the central point maintains its original appearance.
Point Symmetry of a Circle
- Center: The center of the circle serves as the point of symmetry.
- Symmetry Check: A circle is inherently symmetric. Rotating it by any degree around the center results in an identical shape.
Point Symmetry of a Star
- Center: For a symmetrical star, the center is often the midpoint of its vertical axis.
- Symmetry Check: The star shows point symmetry when rotated by certain angles around its central point. Reflection across this point also reveals symmetry.
Point Symmetry
Point Symmetry, or Origin Symmetry, or Central Symmetry is a type of symmetry where an object or shape looks the same when rotated 180° (a half-turn) around a central point.
In this article, we will discuss Point Symmetry in detail including its definition, examples, as well as some real-life examples in nature as well.
