What does a scale factor greater than 1 indicate in a dilation?

• The figure will enlarge

• The figure will rotate

• The figure will shrink

• The figure will remain the same size

Why was the scale factor changed from 3 to 2 in the demonstration?

• To increase the size of the triangle

• To make the triangle smaller

• To fit the dilation on the graph

• To simplify calculations
