Description
"Line Segments, Straight Lines and Rays" Angle PPT Courseware
One side of the blackboard can be regarded as a line segment, and the line segment has two endpoints.
The shortest line segment between two points, the length of the line segment is the distance between the two points.
If the two ends of the line segment are extended infinitely
I would like to ask: (1) How many endpoints does this line have?
(2) Can this line be drawn?
(3) Can this line be measured?
When the two ends of a line segment are extended infinitely, it becomes a straight line. A straight line has no endpoints.
After one end of the line segment is extended infinitely, it becomes a ray, and the ray has only one endpoint.
Decide whether the following statements are correct or not. If there is an error, please point out where it is.
(1) A straight line has only one endpoint. ( )
(2) After infinitely extending both ends of the line segment, it becomes a ray. ( )
(3) A ray is 5cm long. ( )
(4) The straight line is longer than the ray. ( )
Draw a picture.
(1) Draw a 3cm long line segment.
(2) Draw two rays with the following points as endpoints.
