Translation, Reflection, and Rotation

What is translation in geometry?

• Moving a shape or object without changing its size, shape, or orientation.

• Changing the size of a shape or object without moving it.

• Reflecting a shape or object over a line without changing its size or position.

• Rotating a shape or object without changing its size or position.

What is the difference between a line and a ray?

• A line extends infinitely in one direction, while a ray extends infinitely in both directions.

• A line extends infinitely in both directions, while a ray extends infinitely in one direction.

• A line is a straight path that goes on forever, while a ray is a curved path that ends at a point.

• A line has a starting point and an ending point, while a ray has only one endpoint.

What is the difference between a line segment and a ray?

• A line segment has two endpoints, while a ray has one endpoint and extends infinitely in one direction.

• A line segment extends infinitely in one direction, while a ray has a fixed length.

• A line segment has one endpoint, while a ray has two endpoints.

• A line segment is a straight path, while a ray can be curved.
