Fill in the blanks:
(i) A line segment has a definite ...............
(ii) A line segment has ............... end points.
(iii) A ray has ...............
(iv) A line has ............... end point.
(v) Two lines may intersect only at ...............
Answer
(i) A line segment has a definite length.
(ii) A line segment has two end points.
(iii) A ray has one end point.
(iv) A line has no end point.
(v) Two lines may intersect only at one point.
Write (T) for true and (F) for false for each of the statements given below:
(i) An infinite number of lines can be drawn to pass through two given points.
(ii) A ray has a definite length.
(iii) An infinite number of lines can be drawn to pass through a given point.
(iv) Three lines may intersect at the most at three points.
(v) A line cannot be drawn on a paper.
Answer
(i) False — Only one line can be drawn passing through two given points.
(ii) False — A ray extends endlessly in one direction, so it has no definite length.
(iii) True — An infinite number of lines can be drawn through a single given point.
(iv) True — Three lines in a plane meet at the most at three points of intersection.
(v) True — A line extends endlessly in both directions, so it cannot be drawn completely on paper.
