Draw a line and name it is to different ways
Answers
Answer:
Step-by-step explanation:
See the figure . The line segment PQ links the points P and Q. The points P and Q are called the 'endpoints' of the segment. The word 'segment' typically means 'a piece' of something, and here it means the piece of a full line, which would normally extend to infinity in both directions.
A line segment is one-dimensional. It has a measurable length, but has zero width. If you draw a line segment with a pencil, examination with a microscope would show that the pencil mark has a measurable width. The pencil line is just a way to illustrate the idea on paper. In geometry however, a line segment has no width.
Naming of line segments
Line segments are commonly named in two ways:
By the endpoints.
In the figure above, the line segment would be called PQ because it links the two points P and Q. Recall that points are usually labelled with single upper-case (capital) letters. A shorthand way of writing this isThis is read as "line segment PQ". The bar over the two letters indicates it is a line segment, rather than a line, which goes on forever in both directions.
By a single letter.
The segment above would be called simply "y". By convention, this is usually a single lower case (small) letter. This method is often used in the naming the sides of triangles and other polygons.
