Front

What is a line in geometry?

Back

A straight one-dimensional figure that has no thickness and extends infinitely in both directions.

Front

What is a ray?

Back

A part of a line that has a fixed starting point (endpoint) and extends infinitely in one direction.

Front

What is a vertex in geometry?

Back

The point where two or more lines or edges meet, commonly used in the context of angles and polygons.

Front

How is a plane named in geometry?

Back

A plane can be named by any three non-collinear points on the plane or by an uppercase script letter.

Front

What is a collinear point?

Back

Points that lie on the same straight line.

Front

What is a non-collinear point?

Back

Points that do not all lie on the same straight line.

Front

What is an angle?

Back

A figure formed by two rays (sides of the angle) that share a common endpoint (the vertex).

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 a plane in geometry?

Back

A flat two-dimensional surface that extends infinitely in all directions.

Front

What is the definition of a side in a polygon?

Back

A side is a line segment that forms part of the boundary of a polygon.
