Answer: i think you're talking about dilations and there are specific formulas depending on the situation.
for example: the dilation of (x,y) is (-1/2x, -1/2y).
you'd probably need to subtract 2 from whatever measurements of the shape you're working with. i'm not completely sure though
Ethan's mistakes in sorting the shapes into two groups are:
- Shape C does not belong to group 1 because it does not have square corners
- Shape F does not belong to group 2 because it does not have any square corners
<h3>How to spot the mistakes?</h3>
From the complete question (see attachment), the shapes are grouped using the following criteria:
- All the shapes in group 1 have 4 square corners
- All the shapes in group 2 have exactly 1 square corner
Using the above rules, Ethan's mistakes are: shapes C and F are placed in the wrong groups
