- A shape or an object has symmetry if it can be divided into two identical pieces. In a symmetrical shape, one-half is the mirror image of the other half. The imaginary axis or line along which the figure can be folded to obtain the symmetrical halves is called the line of symmetry.

You can find if a shape has a Line of Symmetry by folding it. When the folded part sits perfectly on top (all edges matching), then the fold line is a Line of Symmetry. Here I have folded a rectangle one way, and it didn't work .
Here you will learn about symmetry, including the definition of symmetry, how to recognize a line of symmetry in 2D shapes, and how to identify line of symmetry in figures. Students will first learn about symmetry as a part of geometry in 4th grade.
How do you know if a shape is symmetrical? A 2D shape is symmetrical if a line can be drawn through it and either side is a reflection of the other. You would call this the line of...
Here you will learn about lines of symmetry, including symmetry properties within polygons, angle properties, and symmetry of different line graphs. Students first learn about line symmetry in grade 4 with their work with 2D shapes in geometry.
Key points. To understand symmetry a good understanding of shapes, including regular polygons and triangles, can be helpful. There are two types of symmetry: reflective and rotational. If a shape...
Oct 24, 2023 · Symmetry in mathematics can refer to one of two types. Line (or Plane) symmetry which deals with reflections and mirror images of shapes or parts of shapes in both 2D and 3D. Rotational symmetry which deals with how often a shape looks identical (congruent) when it has been rotated.
Symmetry defines that the shape is identical on both sides when it is divided by a line. The symmetry of different shapes, regular or irregular. Learn about the symmetry of shapes with examples at BYJU’S.
