Introduction

Review the key concept: Reflecting a point or shape across a line involves flipping it over the line so that the line is the perpendicular bisector of the segment joining a point and its image.

9.
Reflect the figure with vertices at (2, 1), (5, 1), and (3, 4) across the line y = x. Write the new vertices.
[3 marks]
10.
A parallelogram with vertices (0, 0), (2, 3), (5, 3), and (3, 0) is reflected across the line y = -x. Provide the new vertices.

11.
Challenge: A flag pole stands at point (4, 2). It is reflected across the line y = x. Where is the pole now?
[4 marks]
12.
Real-world application: A mirror line runs along y = 0. An artist sketches a shape at points (x, y). To create a symmetrical reflection, what steps must they follow to reflect the shape across y = 0?
