reflection symmetry (or bilateral symmetry)
Reflection symmetry, also known as bilateral symmetry, is a concept used in mathematics to describe the property of an object or a figure that can be divided into two congruent halves by a line called the line of symmetry
Reflection symmetry, also known as bilateral symmetry, is a concept used in mathematics to describe the property of an object or a figure that can be divided into two congruent halves by a line called the line of symmetry. This line acts as a mirror, reflecting one half onto the other.
For an object to possess reflection symmetry, each point on one side of the line of symmetry must have a corresponding point on the other side, such that the distance of each point to the line is equal. This means that if an object or figure is folded along the line of symmetry, the two resulting halves should perfectly overlap.
To better understand reflection symmetry, let’s consider a few examples:
Example 1: The letter “A”
The uppercase letter “A” possesses reflection symmetry. The vertical line that passes through the middle of the letter acts as the line of symmetry. If you fold the “A” in half along this line, the two sides would match up perfectly.

Example 2: Square
A square also has reflection symmetry. You can vertically or horizontally divide a square into two equal halves, and each side will mirror the other.

Example 3: Circle
A circle does not have reflection symmetry since it lacks any straight lines that can act as a line of symmetry. If you fold a circle in half, it won’t match up on both sides.

In summary, reflection symmetry (bilateral symmetry) is a property of objects or figures that can be divided into two equal parts by a line of symmetry, resulting in mirror images of each other. This property is found in various shapes and designs, and it helps us identify and classify patterns and structures in mathematics.
