Geometry Basics

Front

What are the endpoints of a ray?

Back

The endpoints of a ray are the two points that define its starting and ending positions.

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 is a line?

Back

A line is a straight path that extends infinitely in both directions and has no endpoints.

Front

What is a line segment?

Back

A line segment is a part of a line that has two endpoints.

Front

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

Back

A ray has one endpoint and extends infinitely in one direction, while a line segment has two endpoints.

Front

What is a vertex in geometry?

Back

A vertex is a point where two or more lines meet.

Front

What is an angle?

Back

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

Front

How do you identify a ray in a diagram?

Back

A ray is usually represented with an arrow at one end, indicating it extends infinitely in that direction.

Front

What does it mean for two rays to be opposite?

Back

Two rays are opposite if they point in exactly opposite directions from a common endpoint.

Front

What is the notation for a ray?

Back

A ray is typically denoted by its endpoint and another point on the ray, such as Ray AB.
