Can you give us the context? :)

There are two shapes on graph paper. One unshaded and one exactly the same but shaded. The question is How many squares have the shaded shapes translated?

Moved.
How far do you have to move a to put it on top of b.

Does this help Bibs?

Look at the top right hand corner of the unshaded square then count how many squares you need to move along and down till you get to the top right hand corner of the shaded square.

Ooo, thanks tilly. So has that first triangle translated 5 squares then? Confused

One way to think of it...
You can move a shape in two ways:
1- rotate it
2- translate it (ie move it without rotating it)

It is only confusing because the word translate has another more common meaning.

SandStorm · 01/05/2012 17:35

Bib - that's right. The triangle has translated 5 squares to the right.

bibbitybobbitybunny · 01/05/2012 17:38

And then is it 6 when it goes up?

(thanks for patience)

Think of translate as 'slide' without turning. Yes, it has translated 5 to the right and 6 up.

Thanks everyone!

Dear God and she is only 11, what am I going to be like when she gets to 16 or 18? No help to her whatsoever!
