Reflections Across Axes

Reflections Across Axes

Introduction

Reflections across axes are geometric transformations that “flip” a point or a shape over a line on the coordinate plane. The most common reflection lines are the x-axis and y-axis. Reflections are useful because they ...

Sarah is learning about reflections on the coordinate plane.

A reflection creates a mirror image of a point across a line, such as the x-axis or y-axis.

Points are written as (x, y), where x-coordinate tells us how far to move left or right, and y-coordinate tells us how far to move up or down.
