If you were asked to draw a scaled copy with a scale factor of 1, the copy will be...

• Larger

• Smaller

• The Same Size

Answer explanation

Scale factor of 1 means you multiply all side lengths by 1. Anything multiplied by 1 is itself, so the lengths are not changing. This means the shape is going to be the same size.
