Reflections Across the Y-Axis: A Mirror Image in Geometry
In geometry, a reflection is a transformation that flips a point or shape over a line, known as the line of reflection. This creates a mirror image of the original object, where the distance between the original and reflected points is equal to the distance between the points and the line of reflection. Understanding Reflections […]
