4.10 - Geometric Lines

Front

What is a ray?

Back

A part of a line that has one endpoint and extends infinitely in one direction.

Front

What is a line?

Back

A collection of points extending infinitely in both directions with no endpoints.

Front

What is a line segment?

Back

A part of a line that has two endpoints.

Front

What is a vertex?

Back

The point where two lines meet.

Front

What is the difference between a line and a ray?

Back

A line extends infinitely in both directions, while a ray has one endpoint and extends infinitely in one direction.

Front

What does it mean for a line to be straight?

Back

A straight line does not curve and is the shortest distance between two points.

Front

What is an angle?

Back

An angle is formed by two rays that share a common endpoint, called the vertex.

Front

How do you identify a vertex in a geometric figure?

Back

The vertex is the point where two lines or rays meet.

Front

What is the symbol for a line?

Back

A line is often represented by two points on the line with a line above them, like AB.

Front

What is the symbol for a ray?

Back

A ray is represented by its endpoint and another point on the ray, like AB with an arrow pointing to the right.
