   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.

   Is every geometrical shape symmetrical in nature?

   • It is not that every geometrical shape is symmetrical in nature. There are many shapes that have no symmetry at all. Such shapes are said to have no line of symmetry. Hence, a geometrical figure is said of having no line of symmetry if it is not symmetrical about any line of axis. Let us consider some examples.

   How do you know if a shape is symmetry?

   • Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes. Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts.

   Do rectangles have the same symmetry?

   • Rectangles have the same interior angles, but they do not have the same side lengths. 2D shapes can have more than one line of symmetry or no lines of symmetry. Lines of symmetry are often confused with rotational symmetry. A line of symmetry on a two-dimensional shape divides the shape equally into two symmetrical pieces.

   How do you know if a 2D 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 symmetry. If you put a mirror on this line, you would see the whole shape in the reflection. That’s why a line of symmetry is sometimes called the mirror line.

   Why do regular shapes have many lines of symmetry?

   • A reason why regular shapes have many lines of symmetry is due to the angles within the shape being the same. As soon as the angles in two-dimensional shapes change from their equal property, the number of lines of symmetry changes. Let’s look at different shapes (specifically quadrilaterals) and their number of lines of symmetry.

   Why does a geometrical figure have no line of symmetry?

   • Hence, a geometrical figure is said of having no line of symmetry if it is not symmetrical about any line of axis. Let us consider some examples. A parallelogram has no line of symmetry. This is because the shape of a parallelogram is such that it cannot be divided into two identical halves in any manner. A scalene no 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 ...
