Points, Lines, Line Segments and Rays

Front

What is a point in geometry?

Back

A point is an exact location 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.

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 segment different from a line?

Back

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

Front

What is the notation for a line segment between points A and B?

Back

The notation is segment AB or AB.

Front

What is the notation for a ray starting at point A and passing through point B?

Back

The notation is ray AB.

Front

Can a point exist in a two-dimensional space?

Back

Yes, a point can exist in a two-dimensional space, represented by coordinates (x, y).

Front

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

Back

Points define locations, lines connect points, and planes are flat surfaces defined by lines and points.

Front

What is the difference between a line and a line segment in terms of length?

Back

A line has no length as it extends infinitely, while a line segment has a measurable length between its endpoints.
