Here you will learn about symmetry, including the definition of symmetry, how to recognize a line of symmetry in 2D shapes, and how to identify line of symmetry in figures. Students will first learn about symmetry as a part of geometry in 4th grade.
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. Identify line-symmetric figures and draw lines of symmetry.

You can see one line of symmetry, two lines of symmetry, and also more lines of symmetry in some shapes or objects. Check some examples of different lines of symmetry shapes below.
Example 1. Which of the following shapes does not have a line of symmetry? Solution: From the given images, only the first one has one line of symmetry. And the second image is asymmetric. When you fold both images, then we can see a line of symmetry in the first image, not in the second image. Example 2. Which of the following is not a line of sym...
1. What is symmetry? The symmetry is the reflection of an image that is similar to the original image. If you take an object or shape and draw a line of symmetry then the image’s first half appears similar to the second half of the image. 2. What are the 4 types of symmetry? The different 4 types of symmetries are 1. Translation symmetry 2. Reflect...
If a shape can be divided through the center such that two identical pieces are formed, the shape is said to be symmetric. How Can We Draw a Symmetric Shape? A symmetric shape has identical parts that mirror each other across the line of symmetry.
How do you know if a 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...
E.g. A rectangle has two lines of symmetry (LoS) shown below using a dashed line. In the diagram on the left, the vertical line of symmetry splits the rectangle into two equal shapes, in the diagram on the right the horizontal line of symmetry splits the rectangle into two equal shapes.

1. Use your ruler to draw a square 4 by 4 in (10.16 by 10.16 cm). 2. Use your ruler to measure the horizontal midpoint of your square at the top and bottom and mark each with a tiny dot (Figure 1).
