- A shape is said to have a reflection symmetry if there exists at least one line that divides a figure into two halves such that one-half is the mirror image of the other half. Thus, it is also known as line symmetry or mirror symmetry.

What does Reflection Symmetry Look Like? For any shape, reflection symmetry looks when a central dividing line (a mirror line) can be drawn on it, proving that both sides of the shape are exactly the same or reflections of one another.

Reflection Symmetry (sometimes called Line Symmetry or Mirror Symmetry) is easy to see, because one half is the reflection of the other half. The reflection in this lake also has symmetry, but in this case: 1. the Line of Symmetryruns left-to-right 2. it is not perfect symmetry, because the image is changed a little by the lake surface.
The Line of Symmetry (also called the Mirror Line) can be in any direction. But there are four common directions, and they are named for the line they make on the standard XY graph. See these examples (the artwork was made using Symmetry Artist) :
Not all shapes have lines of symmetry, or they may have several lines of symmetry. For example, a Triangle can have 3, or 1 or nolines of symmetry: I have collected some more examples at Lines of Symmetry of Plane Shapes.
Dec 14, 2023 · Reflection symmetry happens when a figure can be split into two parts, and one part is like a mirror image of the other. This is also called line symmetry. The dividing line can go in any direction, like up and down, side to side, or at an angle.
Reflection symmetry is also known as line symmetry or mirror symmetry. It states that if there exists at least one line that divides a figure into two halves such that one half is the mirror image of the other half.
In mathematics, reflection symmetry, line symmetry, mirror symmetry, or mirror-image symmetry is symmetry with respect to a reflection. That is, a figure which does not change upon undergoing a reflection has reflectional symmetry. In 2-dimensional space, there is a line/axis of symmetry, in 3-dimensional space, there is a plane of symmetry
In other words, if you can reflect a shape across a line and the shape looks like it never moved, it has reflection symmetry. A rectangle is an example of a shape with reflection symmetry. A line of reflection through the midpoints of opposite sides will always be a line of symmetry.
