Finding Lines of Reflection WORKSHEET DESCRIPTION
This worksheet develops students’ understanding of reflections by focusing on how to identify or construct the correct line of reflection on a coordinate grid.
Section A asks pupils to examine a series of diagrams and decide which ones do not represent a true reflection, encouraging careful comparison of corresponding vertices and equal perpendicular distances.
Section B requires learners to draw the mirror line themselves between an object and its image, reinforcing precision and spatial reasoning.
In Section C, students state the equation of the line of reflection on a coordinate grid using either vertical, horizontal, or diagonal forms.
The final reasoning task challenges pupils to: evaluate a statement as always, sometimes, or never true, spot, explain, and correct errors, and provide an example where a point remains invariant under reflection.
