Points Lines Planes

Front

What is a point in geometry?

Back

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

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 plane in geometry?

Back

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

Front

What does it mean for points to be coplanar?

Back

Points are coplanar if they lie on the same plane.

Front

What is the intersection of two lines?

Back

The intersection of two lines is the point where they meet.

Front

How many points are needed to define a line?

Back

Two points are needed to define a line.

Front

What is the difference between a line segment and a line?

Back

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

Front

What is a ray in geometry?

Back

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

Front

What is a transversal line?

Back

A transversal line is a line that intersects two or more other lines at distinct points.

Front

What are parallel lines?

Back

Parallel lines are lines in the same plane that never intersect.
