Lesson

Let's review transformations of shapes to help us in this lesson.

Choose the picture that shows a turn.

A

B

C

Worked Solution

Idea summary

Translations, reflections and rotations change the position or orientation of the shape, but the shape itself stays the same.

Let's look at what happens when shapes undergo a combination of translations, reflections, or rotations.

What two transformations would be needed to get from Flag A to Flag B?

A

Rotation and translation

B

Two translations

C

Two reflections

D

Reflection and translation

Worked Solution

Idea summary

A shape or object many be transformed more than once. Think about whether the position or orientation of the shape has changed to help work out whether it has been translated, reflected, rotated, or enlarged.

Describe translations, reflections and rotations of two-dimensional shapes. Identify line and rotational symmetries
