A common symmetric figure you can find at home is a rectangular mirror. Its shape is symmetric along both vertical and horizontal axes, meaning that one half is a mirror image of the other. Other examples include a square table, which has four equal sides and angles, and a circular clock, which is symmetric around its center.
Symmetric is a term used to describe an object in size or shape. For example, you could say that an orange is symmetric to the sun or a glass is symmetric to a cone
