Which slider creates scale copies of the shape?
First example: (read the sentences before you watch the video a second time)
In order to create a scale copy you’d want to scale by the same factor.
As we move the slider for shape B, it seems like it’s only scaling the width, it’s not scaling the height.
So, 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.
Second example:
Complete the sentences with the words below:
down - B - factor - increasing - A - width - not - height
This does look like we’re scaling _____, but we’re scaling both the width and the height by the same _________ so shape ____ slider does look like it’s creating scale copies of the shape.
So, the slider for shape ____ is ____ creating scale copies of the original shape. It’s only _______________
the _____ not the _____. It’s elongating it, it’s increasing its height, but not the width.
