What is the name of a transformation that moves a shape without rotating it?

• A. Rotation
• B. Translation
• C. Reflection
• D. Dilation

Answer: (B)

Translation is the transformation that slides a shape to a new position without turning it. When you translate, every point of the shape moves the same distance in the same direction along a straight path, so the figure keeps its size and orientation. The result is just a new location for the same shape, like moving a sticker across a page without rotating it. Because all points move together, distances and angles inside the shape stay exactly the same. This is different from rotations (which spin the shape around a point), reflections (which flip the shape to create a mirror image across a line), and dilations (which change the size of the shape).
