What is a point in geometry?

Back

A point is a specific location in space that has no size, area, length, or volume. It is usually represented by a dot and labeled with a capital letter.

Front

How do you label a point?

Back

A point is labeled with a capital letter, such as A, B, or C.

Front

What are collinear points?

Back

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

Front

Give an example of three collinear points.

Back

P, Q, and R are an example of three collinear points.

Front

What is a line segment?

Back

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

Front

How do you label a line segment?

Back

A line segment is labeled by its two endpoints, such as segment AB.

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.

Front

How do you label a ray?

Back

A ray is labeled with its starting point and another point on the ray, such as ray AB.

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.
