Front

What is a point in geometry?

Back

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

Front

Define a line in geometry.

Back

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

Front

What is a line segment?

Back

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

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 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 the definition of 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 a line and a plane?

Back

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

Front

If points D and F are noncoplanar, what does that imply?

Back

It implies that points D and F do not lie on the same plane.
