Answers
Step-by-step explanation:
(i) Line-segment- Give two points A and B on a line l, the connected part (segment) of the line with end points at A and B is called the line segment AB. (ii) Collinear points – Three or more points are said to be collinear if there is a line which contains all of them. (iii) Parallel lines – Two lines l and m 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 called point of intersection. (v) Concurrent lines – Three or more lines are said to be concurrent if there is a point which lies on all of them. (vi) Ray – A line in which one end point is fixed and the other part can be extended endlessly. (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 half-line.
