Dilation Preserved Properties

Explanation

Dilation is a transformation that changes the size but keeps the same shape (creates similar figures).

Properties preserved under dilation:

1. Angle measures remain the same.

2. Shape similarity is preserved.

3. Proportional lengths: sides are scaled by the scale factor.

Properties not preserved under dilation:

• Absolute distances (sides grow or shrink)

• Orientation (only preserved if center of dilation is fixed)

Example: Dilating a triangle by scale factor 2 → all angles same, all sides double.
