Understand the effect of a scale factor of 1 on a shape.
Remember: scale factor 1 means no enlargement or reduction.
Applying a scale factor of 1 to a shape results in no change in size. All side lengths remain the same, and the shape retains its original dimensions and angles. This concept is essential when studying similar shapes and understanding proportional transformations. Practice identifying the effect of different scale factors on shapes, noting that 1 preserves size, >1 enlarges, and 0
