Points, Lines, and Planes

Front

What is the definition of a point in geometry?

Back

A point is an exact location in space with no length, width, or depth.

Front

What is a line in geometry?

Back

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

Front

What does it mean for points to be collinear?

Back

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

Front

What is the intersection of two lines?

Back

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

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 the intersection of two planes?

Back

The intersection of two planes is a line.

Front

How many points are needed to define a line?

Back

Two distinct points are needed to define a line.

Front

What is a line segment?

Back

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

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 are non-collinear points?

Back

Non-collinear points are points that do not lie on the same straight line.
