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 line segment?

Back

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

Front

What is a ray in geometry?

Back

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

Front

What does it mean for points to be collinear?

Back

Collinear points are points that lie on the same straight line.

Front

What does it mean for points to be coplanar?

Back

Coplanar points are points that lie on the same plane.

Front

What is a plane in geometry?

Back

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

Front

How is a plane named?

Back

A plane can be named by any three non-collinear points on the plane or by a single uppercase script letter.

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 the definition of non-coplanar points?

Back

Non-coplanar points are points that do not lie on the same plane.
