Vocabulary 1.1 Points, Lines, Planes

Front

What is 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 is bounded by two distinct endpoints.

Front

What is a ray?

Back

A ray is a part of a line that starts at a point and extends infinitely in one direction.

Front

What are collinear points?

Back

Collinear points are three or more 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.

Front

What is the intersection of two planes?

Back

The intersection of two planes is a line.

Front

Define a point in geometry.

Back

A point is a precise location or position in space, represented by a dot.

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 difference between a line and a line segment?

Back

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

Front

What is an angle?

Back

An angle is formed by two rays that share a common endpoint, called the vertex.
