Front

What is a point?

Back

A point is a specific location in space that has no size or dimension.

Front

What is a line?

Back

A line is an infinite series of points that extends in both directions without end.

Front

What is a ray?

Back

A ray is a part of a line that starts at a point 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

What is a plane?

Back

A plane is a flat, two-dimensional surface that extends infinitely in all directions.

Front

How is a line represented in geometry?

Back

A line is usually represented by a straight line with arrows on both ends.

Front

How is a ray represented in geometry?

Back

A ray is represented by a straight line with one endpoint and an arrow on the other end.

Front

What notation is used for a line segment?

Back

A line segment is denoted by the endpoints, for example, segment AB.

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 ray?

Back

A ray is denoted by its endpoint and another point, for example, ray AB.
