Geometry A 1.1 Points, Lines, Planes

Front

What is a point in geometry?

Back

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

Front

Define a line in geometric terms.

Back

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

What does it mean for points to be non-coplanar?

Back

Points are non-coplanar if they do not lie on the same plane.

Front

What is the difference between collinear and non-collinear points?

Back

Collinear points lie on the same line, while non-collinear points do not.

Front

How can you identify a line containing a specific point?

Back

A line containing a specific point can be identified by naming the line that passes through that point.

Front

What geometric figure can represent a laser beam?

Back

A laser beam can be represented as a line.

Front

What is the significance of naming a plane?

Back

Naming a plane helps to identify and reference it in geometric discussions.

Front

How do you determine if three points are coplanar?

Back

Three points are coplanar if they lie on the same flat surface.
