In geometry, a line of symmetry in geometric shapes refers to the line that can divide the shape into two, so that each half reflects a mirror image of the other side. Learn more about geometric shapes and lines of symmetry, and then look at an example of a rectangle and an example ...
What is symmetry? We explain what symmetry is and how primary-school children are taught to find the line of symmetry and draw lines of symmetry on different shapes. What is symmetry? Something is symmetrical when it is the same on both sides. A shape has symmetry if a central dividing ...
Symmetry can be observed in many different places in the real world. Therefore, it is important to be familiar with what symmetry is and what lines of symmetry represent. One type of a line of symmetry is a vertical line of symmetry, and these lines are common in mathematical graphs as ...
Take a look in the mirror. Does one side of your face look the same as the other side? There may be slight differences, but your face is symmetrical. In this lesson, you are going to learn about lines of symmetry. Line of Symmetry ...
