Front

What is a point?

Back

A point is a specific location in space that does not take up room or have size.

Front

What do two planes intersect at?

Back

Two planes intersect at a line.

Front

What is a line?

Back

A line is a straight one-dimensional figure that extends infinitely in both directions.

Front

What is a ray?

Back

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

Front

What is a plane?

Back

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

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 a line segment?

Back

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

Front

How many points are needed to define a line?

Back

Two points are needed to define a line.

Front

What is the relationship between points and lines?

Back

A line is defined by at least two points.

Front

What is the definition of a ray?

Back

A ray is defined by an endpoint and extends infinitely in one direction.
