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.
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.
Mar 5, 2024 · For every line in the 2d plane, we can construct a shape with an "inside and outside" (often a circle) such that the shape is cut by the line into two symmetrical parts. Does this property of lines extend to all curves?
Sep 24, 2024 · Lines of Symmetry. The lines of symmetry are the imaginary lines along which a geometrical figure is symmetric in nature. We can classify the lines of symmetry in two types. First one is based on the nature of lines of symmetry which can be further classified as horizontal, vertical or diagonal in nature.
When the folded part sits perfectly on top (all edges matching), then the fold line is a Line of Symmetry.
In order to draw/identify lines of symmetry you need to: Locate the center of the 2D shape. Draw a horizontal and/or vertical line of symmetry through the center of the shape. Draw a line from each vertex through the center to check for all lines of symmetry. State the number of lines of symmetry.

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.
