Reflection with coordinates

 

Notes and Guidance

Children might use mirrors to do this. This might be done through investigation where children record coordinates of vertices of the object and coordinates of vertices of the image in a table.

 

Maths Talk

What is the 𝑥-coordinate for this vertex?

What is the 𝑦- coordinate for this vertex?

If we look at this point, where will its new position be on the image, when it is reflected?

What’s different about the coordinates of the object compared to the coordinates of the image?

Do you always need to use a mirror?

How else could you work out the coordinates of each vertex?
