Lines, Points, Rays, Line Segments

Front

What is a point in geometry?

Back

A point is a precise location or position in space, typically represented by a dot.

Front

What is a line in geometry?

Back

A line is a straight one-dimensional figure that extends infinitely in both directions, having no endpoints.

Front

What is a ray in geometry?

Back

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

Front

What is a line segment?

Back

A line segment is a part of a line that has two endpoints.

Front

How is a line represented in geometry?

Back

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 defined endpoints.

Front

What is the notation for a ray?

Back

A ray is typically denoted by its endpoint and another point on the ray, such as ray AB, where A is the endpoint.

Front

Can a ray be measured?

Back

No, a ray cannot be measured in length because it extends infinitely.

Front

What is the significance of points in geometry?

Back

Points serve as the building blocks for defining lines, line segments, and rays.

Front

How do you identify a line segment in a diagram?

Back

A line segment is identified by two endpoints and is usually represented with a solid line between them.
