Key Facts & Information
At the end of the lesson, the student will learn how to identify symmetrical figures by knowing the technique of drawing symmetry lines.
A Note for the Teacher
When dealing with symmetrical figures, take note of the following:
- Identify if the shape is equilateral.
- Try drawing the line of symmetry in the middle of the figure.
- Always look for the mirror image of each half.
- Symmetrical shapes can be folded in the middle and produce equal-sized halves.
- We can cut a shape into two equal portions if the shape is symmetrical.
- A shape is symmetrical if it has a line of symmetry. A line of symmetry is a line wherein when a line is drawn in the middle of the figure; the right side reflects a similar image on the left side of the shape. Similarly, if an image is folded on the line of symmetry, it will produce halves that match exactly (having equal sizes).
- As long as there is one symmetry line found in an image, it is already proven to be symmetrical.
- Below are examples of figures that are not symmetrical:
- One easy way to find out if the shape is symmetrical is by drawing a symmetry line in the middle of the figure either horizontally or vertically.
- Equilateral shapes are examples of symmetrical shapes.
