Match the following columns:


Column I



Column II



(a)A line segment has a


(b) A ray has the end point


(c) How many lines can be drawn to pass through a given point?


(d) How many lines can be drawn to pass through two given points?



(p) Infinitely many


(q) definite length


(r) B


(s) Only one



The correct answer is:


(a)-………, (b)-……., (c)-…….., (d)………

(A)-(q), (B)-(r), (C)-(p), (D)-(s)


(A)-(q): A line segment has definite length.


Its length can be measured. A line segment AB has two end points A and B. It starts from point A and ends at point B. One and only one line-segment can be between two given points A and B.


(B) – (r): A ray has the end point “B”


A ray is a line with one end. It starts at a given point and goes off in a certain direction forever. Here, the end point is B and it extends infinitely in the direction A.


(C)-(p) Through a point, infinitely many lines can be drawn.


In 1 dimension, only one line can be drawn passing through a single point. However, in 2 or more dimension, uncountably many lines can be draw which pass through one point.


(D)-(s) Only one lines can be drawn to pass through two given points.


Through two given points only one unique line can be drawn.
