Linear Symmetry
More Symmetry
Students should be able to:
- identify and describe line symmetry in two-dimensional shapes and designs.
Introduction to Linear Symmetry: The Letter A
Take a look at the letter below--half of it is missing. See if you can guess what letter it is and then click the button below it to see if you were correct.
What did you notice?
After you clicked the button the right half of the letter A appeared. It looked exactly the same as the left half! Because the two sides of the A look the same, or mirror each other, we say that the A has line symmetry. We call it line symmetry because we can actually draw a line down the middle of the A that divides the letter into two mirror images.
That line is called the line of symmetry. We could also fold the A on the line of symmetry and the two halves would fit perfectly on top of each other!
Another Letter with Line Symmetry
Many letters have more than one line of symmetry. The letter below has two lines of symmetry. See if you can guess what letter it is and then click on the button. It will show you two lines of symmetry.
