Class 6 • Chapter 9: Line of Symmetry, Reflection, and Symmetrical Patterns
Class 6 Section 9.4: When an object is reflected across a mirror line, its mirror image has a left-right reversal, but stays at the exact same distance!
Notice how the distance of any node on the left equals its reflection's distance on the right: Object Distance = Image Distance. The line of reflection acts as a perpendicular bisector!
