Points, Lines, and Planes

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 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 is the intersection of two lines?

Back

The intersection of two lines is the point where they meet or cross each other.

Front

What is the intersection of a line and a plane?

Back

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

Front

What does it mean for two planes to intersect?

Back

Two planes intersect along a line, which is the set of points that are common to both planes.

Front

What is a collinear point?

Back

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

Front

What are coplanar points?

Back

Coplanar points are points that lie on the same plane.

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 starts at a point and extends infinitely in one direction.
