Geometry Rays Lines

How is a ray defined in geometry?

• A line that has a point of origin but extends infinitely in one specific direction.

• A circle with an infinite radius.

• A line segment that connects two points.

• A line that has a point of origin and stops at a specific point.

What is the main characteristic of a ray compared to a line?

• A ray is a closed figure, while a line is an open figure.

• A ray has a defined point of origin, while a line is infinite in both directions.

• A ray is two-dimensional, while a line is three-dimensional.

• A ray has multiple points of origin, while a line has only one.

What are the characteristics of a line in geometry?

• Has an end point

• Has a defined width

• Infinite length, without width or thickness.

• Can be curved

Identify the ray in the following figure: [diagram with a point and a line]

• The point is the ray.

• The figure does not have a ray.

• The ray is invisible.

• The line is the ray.
