Points, Lines, Line Segments, Rays

Front

What is a point in geometry?

Back

A point is a precise location or position in a two-dimensional or three-dimensional space, represented by a dot and having no size or dimension.

Front

Define a line in geometry.

Back

A line is a straight one-dimensional figure that extends infinitely in both directions, having no endpoints.

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 (the endpoint) and extends infinitely in one direction.

Front

How do you denote a ray?

Back

A ray is denoted by its endpoint and another point on the ray, using the notation 'Ray AB', where A is the endpoint.

Front

What distinguishes a line from a line segment?

Back

A line extends infinitely in both directions, while a line segment has two endpoints and a finite length.

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 and a finite length.

Front

How can you identify a ray in a diagram?

Back

A ray can be identified by its starting point and the direction it extends, often represented with an arrow at one end.

Front

What is the notation for a line segment?

Back

A line segment is denoted by its two endpoints, for example, 'Line Segment AB'.

Front

What is the significance of points in defining lines and segments?

Back

Points are used to define the positions of lines and segments; a line is defined by any two points, and a segment is defined by its two endpoints.
