Front

Define a point in geometry.

Back

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

Front

What is a line in geometry?

Back

A line is a straight one-dimensional figure that extends infinitely in both directions, defined by any two points on it.

Front

What is a line segment?

Back

A line segment is a part of a line that is bounded by two distinct endpoints.

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

Define a plane in geometry.

Back

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

Front

What does it mean for points to be coplanar?

Back

Points are coplanar if they lie on the same plane.

Front

How can a line be named?

Back

A line can be named by any two points on the line or by a lowercase script letter.

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

What is a hexagon?

Back

A hexagon is a polygon with six sides and six angles.
