Mirror Symmetry Study Guide
Definition
Mirror symmetry refers to the property of an object or shape to be reflected in a mirror and maintain its proportions and angles.Properties
- When an object is reflected in a mirror, the distance from the object to the mirror is the same as the distance from the image to the mirror.
- The angles formed by the object and its reflection are congruent.
- Parallel lines in the object remain parallel in its reflection.
Examples
Some examples of mirror symmetry include:
- A square has mirror symmetry along its sides.
- A circle has mirror symmetry along any line passing through its center.
- The letter "H" has mirror symmetry along its vertical line of symmetry.
Applications
Mirror symmetry has practical applications in various fields such as architecture, art, and design. Understanding mirror symmetry helps in creating balanced and visually appealing designs.Exercises
Practice identifying mirror symmetry in different shapes and objects. Draw lines of symmetry and verify the properties of mirror symmetry in each case.
