Reflections

Reflections Transformations

Starter Objective: Recap on vertical & horizontal lines.

Name the line y = 6 y = x X = 5 X = -1 Vertical lines are x = y = 1 Horizontal lines are y =

Lesson Objective: Reflect shapes in a given mirror line.

Reflect this triangle in the line x = 5

Check using tracing paper or a mirror

Reflect this rectangle in the line x = 1

Reflect this hexagon in the line x = 4

Reflect this rectangle in the line y = 2

Reflect this trapezium in the line y = 1

Reflect this trapezium in the line y = x

Name the line y = x + 4 y = x y = x + 1 y = -x + 3 y = -x

Reflect this triangle in the line y = - x

Check image using tracing paper

Reflect object in the line y = - x + 6

Check image using tracing paper

Challenge: Reflect the triangle in the y axis, then reflect that triangle in the line y = x.

Challenge: Reflect the triangle in the y axis. Then reflect that triangle in the line y = x. y = x

Challenge: Then reflect that triangle in the line y = x. y = x

Lesson Objective: Describing reflections. Draw and name the mirror line.

Draw in the mirror line and describe the reflection Reflection in the line x = 1

Draw in the mirror line and describe the reflection Reflection in the line y = 2

Draw in the mirror line and describe the reflection

Reflection in the line y = 3

Reflection in the line x = 5

Reflection in the x axis ( the line y = 0 )

Reflection in the y axis ( the line x = 0 )

Reflection in the line y = x

Reflection in the line y = - x
