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 and has no thickness.

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 collinear?

Back

Points are collinear if they lie on the same straight line.

Front

How can you identify a line that contains a specific point?

Back

A line that contains a specific point can be identified by checking if the point lies on the line.

Front

What is the relationship between lines and planes?

Back

A line can lie in a plane, intersect a plane, or be parallel to a plane.

Front

What is an example of coplanar points?

Back

Points A, B, and C can be an example of coplanar points if they lie on the same plane.

Front

What is the significance of the term 'collinear' in geometry?

Back

Collinear points are important for understanding the properties of lines and their relationships.

Front

True or False: A line can be defined by two points.

Back

True, a line can be uniquely defined by any two distinct points.
