Points, Lines, and Planes

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 does it mean for points to be coplanar?

Back

Points are coplanar if they lie on the same plane.

Front

How do two lines intersect in a plane?

Back

Two lines intersect at a point if they are not parallel and lie in the same plane.

Front

What is the intersection of two planes?

Back

The intersection of two planes is a line, provided the planes are not parallel.

Front

What is a line segment?

Back

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

Front

Define parallel lines.

Back

Parallel lines are lines in the same plane that never intersect and are always the same distance apart.

Front

What are skew lines?

Back

Skew lines are lines that do not intersect and are not parallel, existing in different planes.

Front

What is the significance of a point of intersection?

Back

A point of intersection is where two geometric figures meet or cross each other.
