Geometry

Question Analysis

The main focus is to determine whether the dilation is an enlargement or a reduction and find the scale factor when the origin is the center of dilation, by comparing the coordinates of corresponding points in the original and dilated figures.

Key Concept Explanation

If the scale factor k>1, the dilation is an enlargement; if 0 < k < 1, it's a reduction. For a dilation centered at the origin, the scale factor can be calculated as for a point and its image
