pdf Reflection Across X And Y-axis

This reflections worksheet provides focused practice on reflecting figures across both the x-axis and the y-axis on the coordinate plane. Students review the reflection rules, apply them to multiple polygons, and determine how coordinates change when reflected.

The resource begins with a clear example demonstrating that when reflecting across the x-axis, only the y-values change sign, modeled by \((x, y) \rightarrow (x, -y)\). When reflecting across the y-axis, only the x-values change sign, modeled by \((x, y) \rightarrow (-x, y)\). Students then apply these rules to quadrilaterals, arrows, and triangles, drawing reflected figures and listing the new coordinates.

In addition to coordinate calculations, students analyze quadrant changes after reflection, strengthening their conceptual understanding of how rigid transformations affect position but preserve shape and size.
