Line Symmetry Worksheets

What is Line Symmetry? We often find symmetrical things around us. We call an object symmetrical to the other one when there is an exact reflection or mirror image. A particular object, line, or shape is formed. The line of symmetry can be defined as the axis or an imaginary line that passes through an object or shape dividing it into two identical and equal parts. For instance, we have the following shapes:

Here, the dotted line is the line of symmetry. The above shapes are divided by the line of symmetry and these figures have an exact resemblance to each other. They are also divided into two equal parts.

• Basic Lesson

Guides students through identifying line symmetry with real world applications. Line symmetry is two halves of figure mirror each other across a line. The line of symmetry is line that divides the figure into two mirror images. A simple test to determine line symmetry of a figure is to fold the figure along the supposed line of symmetry and check the two halves of the figure coincide.
