we are told drag the sliders and then they say which slider creates a scale copy of the shape or which slider creates a scale copies of the shape so let's just see explore this a little bit okay that's pretty neat these sliders seem to change the shape in some way and in different ways so shape B right over here so it starts off it looks like the width is a little bit bigger than the height I'm just trying to eyeball it we don't know the exact numbers and so in order to create a scaled copy you'd want to scale the width you'd want to scale this bottom side and the top side and all of the sides you would want to scale by the same factor but as we move this slider it seems like it's only scaling the width it's not scaling the height so this slide our shape B right over here the slider for shape B is not creating scale copies of itself it's only increasing the width not the height while shape a it looks like it is increasing both the width and the height so that would be a scale copy so for example that looks like a scaled copy of this which looks like a scale copy of this which looks like a scaled copy of that which was our original shape that is not a scaled copy of this let's do another example so once again they say drag the sliders and they say which slider creates a scale copy of the shape I let's get shape a so this does look like we're scaling down but we're scaling both the width and the height by the same factor so shape this shape a slider does look like it's creating scale copies of the shape B right over here well now we're only scaling it looks like we're only scaling the height but not the width so this is not creating scale copies of our original shape it's elongating it it's it's increasing its height but not the width
