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

What is a line in geometry?

Back

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

How many points are needed to define a plane?

Back

At least three non-collinear points are needed to define a plane.

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 the point where they meet or cross each other.

Front

How is a line named in geometry?

Back

A line can be named using any two points on the line or a lowercase letter.

Front

What is the difference between a line segment and a line?

Back

A line segment has two endpoints and a fixed length, while a line extends infinitely in both directions.

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 is a transversal line?

Back

A transversal line is a line that intersects two or more other lines at distinct points.
