Lines, Line Segment, Ray, Point

Front

What is a point in geometry?

Back

A point is a precise location or position in space that has no dimensions, represented by a dot.

Front

Define a line in geometry.

Back

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

Front

What is a line segment?

Back

A line segment is a part of a line that is bounded by two distinct endpoints.

Front

What is a ray in geometry?

Back

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

Front

How is a line different from a line segment?

Back

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

Front

What are the characteristics of a ray?

Back

A ray has one endpoint and extends infinitely in one direction.

Front

Can a point be defined in a coordinate system?

Back

Yes, a point can be defined in a coordinate system using ordered pairs (x, y) in 2D or (x, y, z) in 3D.

Front

What is the relationship between points, lines, and planes?

Back

Points define locations, lines connect points, and planes are flat surfaces that extend infinitely in two dimensions.

Front

How do you represent a line segment?

Back

A line segment is represented by its endpoints, for example, segment AB is denoted as AB.

Front

What is the notation for a ray?

Back

A ray is denoted by its endpoint and another point on the ray, for example, ray AB starts at A and passes through B.
