Lesson

Let try this problem to review transformations of shapes .

Choose the picture that shows a translation.

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.

This video starts by recapping translations, reflections, and rotations. It then explores how to identify a shape that has undergone multiple transformations.

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.

Investigate combinations of translations, reflections and rotations with and without the use of digital technologies
