How do you label a ray?

Back

A ray is labeled with two points, with an arrow indicating the direction, e.g., \( \overrightarrow{xy} \).

Front

Define coplanar points.

Back

Coplanar points are points that lie on the same plane.

Front

What is the definition of collinear points?

What is a ray?

Back

A ray is a part of a line that starts at one endpoint and extends infinitely in one direction.

Front

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

Back

A line extends infinitely in both directions, while a line segment has two endpoints.

Front

What is the notation for a line?

Back

A line is typically denoted by two points on the line with a double-headed arrow above them, e.g., \( \overleftrightarrow{AB} \).
