Define the following terms :
(i) Line segment
(ii) Collinear points
(ii) Parallel lines
(iv) Intersecting lines
(v) Concurrent lines
(vi) Ray
(vii) Half-line
Answers
Answer:
(i) Line segment: The part of a line that connects two points or we can say that a shortest distance between the two points. A line segment is one-dimensional.
(ii) Collinear points: Two or more points are said to be collinear if all the points lie on same line.
(iii) Parallel lines : Two lines in a plane are said to be parallel lines if they do not intersect each other.
(iv) Intersecting lines: Two lines are intersecting if they have a common point. The common point is known as point of intersection.
(v) Concurrent lines: Two or more lines are said to be concurrent if there is a point which lies on all of them.
(vi) Ray: A straight line extending from a point indefinitely in one direction only.
(vii) Half-line: If A, B. C be the points on a line l, such that A lies between B and C, and we delete the point A from line l, the two parts of l that remain are each called a half-line.
Step-by-step explanation:
line segment
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints.
collinear point:
Three or more points , , , ..., are said to be collinear if they lie on a single straight line. . A line on which points lie, especially if it is related to a geometric figure such as a triangle, is sometimes called an axis.
parallel line:
Description In geometry, parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel
insecting lines:
Description The notion of line or straight line was introduced by ancient mathematicians to represent straight objects with negligible width and depth.
concurrent lines:
Description Lines in a plane or higher-dimensional space are said to be concurrent if they intersect at a single point
Ray:
The notion of line or straight line was introduced by ancient mathematicians to represent straight objects with negligible width and depth. Lines are an idealization of such objects
half line:
The notion of line or straight line was introduced by ancient mathematicians to represent straight objects with negligible width and depth. Lines are an idealization of such objects
