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.
Feb 1, 2010 · Shapes can be classified according to their symmetry. To do so (for finite shapes, like polygons), count the number of lines of (reflection) symmetry, if any, and determine the (smallest) angle of rotation symmetry, if any.
What are lines of symmetry? Lines of symmetry are straight lines that divide a shape into two equal parts where one part is an exact reflection of the other. E.g. A rectangle has two lines of symmetry (LoS) shown below using a dashed line.

In Mathematics, a meaning of symmetry defines that one shape is exactly like the other shape when it is moved, rotated, or flipped. Consider an example, when you are told to cut out a ‘heart’ from a piece of paper, don’t you simply fold the paper, draw one-half of the heart at the fold and cut it out to find that the other half exactly matches the ...
The imaginary line or axis along which you fold a figure to obtain the symmetrical halves is called the line of symmetry. It basically divides an object into two mirror-image halves. The line of symmetry can be vertical, horizontal or diagonal. There may be one or more lines of symmetry.
Symmetry may be viewed when you flip, slide or turn an object. There are four types of symmetry that can be observed in various situations, they are: 1. Translation Symmetry 2. Rotational Symmetry 3. Reflection Symmetry 4. Glide Symmetry
The symmetry of shapes can be identified whether it is a line of symmetry, reflection or rotational based on the appearance of the shape. The shapes can be regular or irregular. Based on their regularity, the shapes can have symmetry in different ways. Also, it is possible that some shapes does not have symmetry. For example, a tree may or may not ...

Folding Test. 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. So this is not a Line of Symmetry.
A given line has a line of symmetry or it is symmetrical about a line if the line divides a given figure into two identical halves. The line is called the axis of symmetry or line of symmetry. There are two types of lien symmetries according to which we can classify the symmetries in different geometrical figures – Horizontal Lines of ...

What is line symmetry example?
Symmetry is when a line is drawn through a shape to make one side of the line a reflection of the other. Symmetry is a property of 2D and 3D geometrical shapes and objects that divides them into two identical halves that mirror, or are mirror images of each other.
