Front

What is a point in geometry?

Back

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

Front

Define a line in geometric terms.

Back

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

Front

What is a plane in geometry?

Back

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

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

Define a line segment.

Back

A line segment is a part of a line that has two endpoints.

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 or cross each other.

Front

What is the intersection of a line and a plane?

Back

The intersection of a line and a plane is the point where the line crosses the plane.

Front

What does noncoplanar mean?

Back

Noncoplanar points are points that do not lie on the same plane.
