Key Concepts

Reflection in the line y=x

Reflecting a point in the line y=x involves swapping the x and y coordinates of the point. For any point (x, y), this reflection transforms it into (y, x), effectively mirroring the point across the line where x and y are equal.

Reflection in the y-axis

When a point is reflected in the y-axis, the y-coordinate remains unchanged and the x-coordinate's sign is inverted. Thus, for any point (x, y), the reflection in the y-axis results in (-x, y), creating a mirror image across the vertical axis.

Reflection Transformation

A reflection is a geometric transformation that creates a mirror image of a point or shape over a specific line, known as the line of reflection. This process is an isometry, meaning that it preserves distances and angles, resulting in a congruent figure whose location and orientation have changed relative to the mirror line.

Reflection in the x-axis

Reflecting a point in the x-axis involves keeping the x-coordinate the same while reversing the sign of the y-coordinate. For any point (x, y), its image under this reflection is (x, -y), which essentially flips the point vertically across the horizontal axis.
