What does it mean for points to be coplanar?

Back

Points are coplanar if they lie on the same plane.

Front

What is a noncoplanar point?

Back

A noncoplanar point is a point that does not lie on the same plane as other points.

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

How do you name a ray?

Back

A ray is named using its endpoint and another point on the ray, e.g., Ray AB.

Front

What is the notation for a line segment?

Back

A line segment is denoted by the endpoints with a line over them, e.g., segment AB.

Front

What is an angle?

Back

An angle is formed by two rays that share a common endpoint.
