Answer:
Stretch
Step-by-step explanation:
- Translation: A translation moves a shape up, down or from side to side but it does not change its size.
- Reflection: A reflection is a transformation which all the points of an object reflect or flip on a line called the axis of reflection or line of reflection. This transformation does not change its size.
- Rotation: A rotation is a transformation that turns a figure about a fixed point called the center of rotation. This transformation does not change figure's size.
- Stretch: A stretch is a transfoormation which stretch the figure (by multiplying by C>1). This transformation changes the size of the figure.
- Isometry: An isometry is a type of transformation that preserves the length of a figure's sides.
Thus, a stretch is not an isometry
