Points, Lines, and Planes

Front

What is a point in geometry?

Back

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

Front

What is a line in geometry?

Back

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

Front

What is a line segment?

Back

A line segment is part of a line that has two endpoints and includes all points between them.

Front

What is a ray in geometry?

Back

A ray is part of a line that has one endpoint and extends infinitely in one direction.

Front

Define a plane in geometry.

Back

A plane is a flat surface made up of points that has two dimensions and extends infinitely.

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 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 the definition of an angle?

Back

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

Front

How can you identify collinear points?

Back

Collinear points can be identified if they lie on the same straight line.

Front

What is the significance of endpoints in a line segment?

Back

Endpoints define the start and end of a line segment, distinguishing it from a line.
