(i) False

Because a line segment has two end points with a definite length. (ii) False

Because a ray has one end point and infinitely extends in one direction. (iii) False

Because a line has no beginning point or end point therefore a line has not definite length. (iv) True

Because a line has no beginning point or end point therefore line is the same as line . (v) False

Because a ray has one end point and infinitely extends in one direction therefore ray is not same as the ray . In this ray has the end point A. In this ray has the end point B.

(vi) True

Because a line has no beginning point or end point. (vii) True

Because the set of lines intersect at the same point called concurrent lines. Lines l, m, and n are concurrent at the common point P.

(viii) True

Two lines in a plane that do not intersect or touch each other at any point, they are called parallel lines. (ix) True

Because parallel lines never intersect or cross one another. (x) False

Because half-line is the set of all points on a line on a given side of a given point of the line while ray is a part of line with one end point and infinitely extends in one direction.

(xi) False

Because two lines intersect at only one point. Lines l and n intersect at only one point P.

(xii) False

Two lines are said to be parallel when

(a) they never meet

(b) they are coplanar Rate this question :
