For example, different shapes like square, rectangle, circle are symmetric along their respective lines of symmetry. What is a Symmetrical Shape? A 2D shape can be called symmetrical if a line can be drawn through it and either side is a reflection of the other.
In mathematics, an object is said to have symmetry if it can be divided into two identical halves. The line that divides the object into its identical halves is called the line of symmetry. For example, in the given image, the line passing through the middle of the flower is its line of symmetry.
When an imaginary line is drawn through a shape to make one side of the line a true reflection of the other (and vice versa), the shape is known as symmetrical. Examples of objects in the real world that are symmetrical include snowflakes, the feathers of peacocks, and the wings of butterflies.
What are shapes with lines of symmetry? In mathematics, symmetry is something that has similar, or matching, parts. But what makes symmetrical shapes symmetrical? Simply put, symmetrical shapes have one side that is the same as the other. Symmetrical shapes look the same after being reflected, rotated or translated.
Learn and practice identifying lines of symmetry in shapes with interactive resources from GeoGebra. Identify and make figures with line symmetry. Identify the number of lines of symmetry in a figure and draw lines of symmetry.
A square is an example of a regular shape that has symmetry. The left side of a square is a mirror image of the right side, as can be seen, if you draw a vertical line of symmetry through it. If objects do not have a line of symmetry, it is referred to as asymmetric.
Some shape may have two or more lines of symmetry like a circle has infinite lines of symmetry. A square has four lines of symmetry. A rectangle has two lines of symmetry.
