Geometry

Question Analysis  

The main focus is to determine the effect of a negative fractional scale factor on a polygon, analyzing whether it results in enlargement/reduction and reflection/rotation.  

Key Concept Explanation  

Magnitude of : < 1, so the polygon is reduced (shrunk).  

Sign of : The negative sign reflects the polygon across the origin (equivalent to a rotation).  

Step-by-Step Solution  

1. Recognize that (less than 1) → reduction occurs.  

2. The negative sign in → reflection across the origin (no rotation involved, but reflection is a key effect).  

Option Analysis  

A: "Reduced and reflected."  

Correct. |k| < 1 reduces the polygon, and the negative sign reflects it.  

B: "Enlarged and rotated
